Select the correct answer.
during the summer, jody earns $10 per hour babysitting and $15 per hour doing yardwork. this week she worked 34 hours and earned $410.
if x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models
this situation?
a.
x+ y = 34
10x+ 15y = 410
ob. x + y = 410
10x + 15y = 34
c.
x+ y = 34
15x+10y= 410
od. x + y = 410
15x+10y = 34

A

Step-by-step explanation:

x+y=34 (add the seperate hours together to get the total amount of hours)

10x+15y=410 (multiply the money made each hour by the hours worked and add them together to get the amount of money joy made)

A.  

x + y = 34

10x + 15y = 410

Step-by-step explanation:

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
