Answer:
12 1/7 cars
Step-by-step explanation:
Let the number of cars she'd wash to earn $63 in spending money be A.
Given she saves $22 of her weekly earnings and wants to have at least $63 for spending money.
That means she’d have to make $63 + $22 = $85
The expression is thus
$85 = A x $7
Where A is the number of cars and $7 is the amount she earns for washing one car and $85 is the total amount she has to make .
Therefore,
85 = A x 7
Divide both sides by 7
85/7 = A x 7/7
12 1/7 = A
A = 12 1/7 cars
She must wash 12 1/7 cars to have at least $63 spending money and also have her weekly Savings of $22
