Question

Claudia earns the same dollar amount each hour she works. Last weekend, she worked a total of 9 hours and earned $72. Which equation can be used to find the total amount Claudia earns, y, for any number of hours, x, she works?

Answer 1

y=8x can be used to find the total amount earned by Claudia.

Step-by-step explanation:

let,

x be the number of hours and y be the amount earned.

She earned $72 for 9 hours;

9x=72

Dividing both sides by 9;

$\frac{9x}{9}=\frac{72}{9}\\x=8$

Therefore she earns 8 dollars per hour.

As the amount is same, therefore,

Amount earned = Amount per hour * No. of hours

$y=8*x\\y=8x$

y=8x can be used to find the total amount earned by Claudia.
