Answer:

A. 25n + 15x

B. $358.75

Step-by-step explanation:

Jocelyn earns

Grocery store= $x per hour

Babysitting= $n per hour

A. Write an expression that describes her earnings if she babysat for 25 hours and worked at the grocery store for 15 hours.

The expression is:

25n + 15x

B. How much money did she earn if she charged $10 an hour for babysitting and earned $7.25 an hour at the grocery store.

25n + 15x

When n= $10 and x= $7.25

25n + 15x

= 25(10) + 15(7.25)

= 250 + 108.75

= $358.75

Therefore, if Jocelyn earns $10 per hour for babysitting and babysat for 25 hours, and earn $7.5 per hour at the grocery store and works for 15 hours.

Her total earnings will be $358.75
