Select the correct answer:

During the summer, Jody earns [tex]$\$[/tex]10[tex]$ per hour babysitting and $[/tex]\[tex]$15$[/tex] per hour doing yard work. This week she worked 34 hours and earned [tex]$\$[/tex]410[tex]$. If $[/tex]x[tex]$ represents the number of hours she babysat and $[/tex]y$ represents the number of hours she did yard work, which system of equations models this situation?

A. [tex]$x + y = 34$[/tex]
[tex]$10x + 15y = 410$[/tex]

B. [tex]$x + y = 410$[/tex]
[tex]$10x + 15y = 34$[/tex]

C. [tex]$x + y = 34$[/tex]
[tex]$15x + 10y = 410$[/tex]

D. [tex]$x + y = 410$[/tex]
[tex]$15x + 10y = 34$[/tex]



Answer :

In this problem, we need to find the correct system of linear equations that models the given situation about Jody's work hours and earnings.

Let's start by defining the variables:
- \( x \): the number of hours Jody babysat.
- \( y \): the number of hours Jody did yardwork.

According to the problem, Jody worked a total of 34 hours. This gives us the first equation:
[tex]\[ x + y = 34 \][/tex]

Next, we know that Jody earns \[tex]$10 per hour babysitting and \$[/tex]15 per hour doing yardwork. This week, she earned a total of \$410. Thus, we can write the second equation based on her earnings:
[tex]\[ 10x + 15y = 410 \][/tex]

Now, we need to identify the system of equations from the given options:

### Option A
[tex]\[ x + y = 34 \][/tex]
[tex]\[ 10x + 15y = 410 \][/tex]

### Option B
[tex]\[ x + y = 410 \][/tex]
[tex]\[ 10x + 15y = 34 \][/tex]

### Option C
[tex]\[ x + y = 34 \][/tex]
[tex]\[ 15x + 10y = 410 \][/tex]

### Option D
[tex]\[ x + y = 410 \][/tex]
[tex]\[ 15x + 10y = 34 \][/tex]

Comparing each option to our formulated system of equations:

- Option A has the system:
[tex]\[ x + y = 34 \][/tex]
[tex]\[ 10x + 15y = 410 \][/tex]
Which matches our equations.

- Option B has the system:
[tex]\[ x + y = 410 \][/tex]
[tex]\[ 10x + 15y = 34 \][/tex]
Which does not match our equations.

- Option C has the system:
[tex]\[ x + y = 34 \][/tex]
[tex]\[ 15x + 10y = 410 \][/tex]
Which has the coefficients of \( x \) and \( y \) swapped in the second equation. Therefore, it does not match.

- Option D has the system:
[tex]\[ x + y = 410 \][/tex]
[tex]\[ 15x + 10y = 34 \][/tex]
Which does not match our equations.

Based on our comparisons, Option A is the correct system of equations that models the situation.

Therefore, the correct answer is:
[tex]\[ \boxed{1} \][/tex]
