Homework for Chapter B: Percentages and Exponential Functions

Suppose your school costs for this term were $5620 and financial aid covered 75% of that amount.

1. How much did financial aid cover? $__________
2. How much do you still have to pay? $__________



Answer :

Sure, let's solve this step-by-step.

1. Identify the Total School Cost:
The total cost for the term is given as $5620.

2. Determine the Percentage of Financial Aid:
Financial aid covers 75% of the total school cost.

3. Calculate the Amount Covered by Financial Aid:
To find out how much financial aid covers, we need to calculate 75% of $5620.
[tex]\[ \text{Financial aid coverage} = 75\% \times 5620 \][/tex]
Converting 75% to a decimal gives us 0.75.
[tex]\[ \text{Financial aid coverage} = 0.75 \times 5620 = 4215 \][/tex]
So, the financial aid covers $4215.

4. Calculate the Amount You Still Have to Pay:
To find the amount you still need to pay, subtract the financial aid coverage from the total school cost.
[tex]\[ \text{Amount to pay} = 5620 - 4215 = 1405 \][/tex]
Therefore, the amount you still have to pay is $1405.

To summarize:
- Financial aid covers: $4215
- Amount you still have to pay: $1405
