Question

A cashier earns $7 an hour. If x is the number of hours worked, which function represents the cashier’s earnings? y = 7x y = x 7 y = 7/x y=7

Answer 1

I think its 7x since x represents the hours she worked. So lets say that she worked for 5 hours this day. It would be 5*7 which is $35. So it is 7x and if there is any choices you might say it as well so we can help you better

Answer 2

y= 7x

Explanation:

A cashier earns $7 an hour. If x is the number of hours worked,

y be the cashier's earning

To find cashier's earning we multiply the amount earns in 1 hour by the total number of hours worked

Total earnings depends on the total number of hours worked

Total earnings = earning per hour * number of hours worked

Cashier's earnings = 7 * x= 7x

y= 7x
