1. Large cheese pizzas cost [tex]$\$[/tex] 5[tex]$ each, and large one-topping pizzas cost $[/tex]\[tex]$ 6$[/tex] each.

Write an equation that represents the total cost, [tex]$T$[/tex], of [tex]$c$[/tex] large cheese pizzas and [tex]$d$[/tex] large one-topping pizzas.

2. Jada plans to serve milk and healthy cookies for a book club meeting. She is preparing 12 ounces of milk and 4 cookies per person. Including herself, there are 15 people in the club. A package of cookies contains 24 cookies.

A 1-gallon jug of milk contains 128 ounces and costs [tex]$\$[/tex] 3[tex]$. Let $[/tex]n[tex]$ represent the number of people in the club, $[/tex]m[tex]$ represent the ounces of milk, $[/tex]c[tex]$ represent the number of cookies, and $[/tex]b$ represent Jada's budget in dollars.

Select all of the equations that could represent the quantities and constraints in this situation.

A. [tex]$m = 12 \times 15$[/tex]
B. [tex]$3m + 4.5c = b$[/tex]
C. [tex]$4n = c$[/tex]
D. [tex]$b = 2(3) + 3(4.50)$[/tex]



Answer :

### Solution:

#### Part 1: Equation for the Total Cost of Pizzas

To determine the total cost \( T \) of \( c \) large cheese pizzas and \( d \) large one-topping pizzas, we can use the following information:

- Each large cheese pizza costs \$5.
- Each large one-topping pizza costs \$6.

The equation representing the total cost \( T \) is:
[tex]\[ T = 5c + 6d \][/tex]

#### Part 2: Representing Quantities and Constraints

For the book club meeting, we need to consider the quantities and constraints given:

- Jada is preparing for 15 people.
- Each person needs 12 ounces of milk.
- Each person gets 4 cookies.
- A package of cookies contains 24 cookies.
- A 1-gallon jug of milk contains 128 ounces and costs \$3.

We will create equations that link these quantities and constraints.

Equation A: Total Ounces of Milk Needed
[tex]\[ m = 12 \times 15 \][/tex]
Each of the 15 people needs 12 ounces of milk, so:
[tex]\[ m = 180 \][/tex]

Equation B: Budget Equation Combining Milk and Cookies
[tex]\[ 3m + 4.5c = b \][/tex]
The cost of milk is \[tex]$3 per gallon, and the cost of cookies is \$[/tex]4.50 per package.

Equation C: Total Cookies Needed
[tex]\[ 4n = c \][/tex]
Since each of the 15 people (including Jada) gets 4 cookies:
[tex]\[ c = 4 \times 15 \][/tex]
[tex]\[ c = 60 \][/tex]

Equation D: Number of Cookies in Terms of Packages
[tex]\[ c = 4 \text{ packages} \][/tex]
Although this is written differently, it signifies the total number of cookies equivalent to 4 packages, with each package containing 24 cookies:
[tex]\[ c = 4 \times 24 = 96 \][/tex]

Equation E: Calculation of Budget for Specific Values \( n = 2 \) and \( m = 3 \)
[tex]\[ b = 2 \times 3 + 3 \times 4.5 \][/tex]
[tex]\[ b = 6 + 13.5 \][/tex]
[tex]\[ b = 19.5 \][/tex]

Here are the corresponding equations:

1. Total Cost of Pizzas:
[tex]\[ T = 5c + 6d \][/tex]

2. Equations from Book Club Scenario:
- Total ounces of milk needed:
[tex]\[ m = 12 \times 15 \][/tex]

- Budget equation:
[tex]\[ 3m + 4.5c = b \][/tex]

- Total cookies needed:
[tex]\[ 4n = c \][/tex]

- Number of cookies as packages:
[tex]\[ c = 4 \text{ packages} \][/tex]

- Budget calculation for specific values:
[tex]\[ b = 2 \times 3 + 3 \times 4.5 \][/tex]

Thus, the selected equations representing the quantities and constraints in this situation are:

- A. \( m = 12 \times 15 \)
- B. \( 3m + 4.5c = b \)
- C. \( 4n = c \)
- E. \( b = 2 \times 3 + 3 \times 4.5 \)

These equations cover the total amount of milk, budget considerations, total cookies needed, and a budget calculation verifying specific values.
