On monday, nita earned $85 for h hours of babysitting. on wednesday, she earned the same rate for 8 hours of babysitting and got a $12 tip. write an expression to represent how much nita earned on wednesday.

You don’t know how long or how much she got paid an hour on Monday.  All you know is:

h = total number of hours she babysat on Monday, and she made $85.

Let r = the rate she got paid per hour on Monday, then rh = 85, and then r = 85/h

On Wednesday she babysat 8 hours at the same rate of 85/h and got an additional $12

The expression for how much she made on Wednesday is:   8(85/h) + 12

i got 86 for this

hope this !
