Joe told Mickey he got an hourly raise at work and his new rate will be $10.25 per hour. Mickey wants to know what Joe’s hourly rate was before his raise. If r represents the amount of the raise, which expression represents Joe’s hourly rate before his raise? r minus 10.25
10.25 minus r
10.25 + r
r + 10.25

10.25 minus r

Step-by-step explanation:

because amount of money minus how much the raise was equals what he had before.

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams
