You have $20 and earn $0.75 for each cup of orange juice you sell. Write an equation that represents the total amount A (in dollars) you have after selling j​ cups of orange juice.

A= 20 + 0.75*j

Step-by-step explanation:

Giving the following information:

You have $20 and earn $0.75 for each cup of orange juice you sell.

To calculate the total amount of dollars (A), we need to use the following formula:

A= 20 + 0.75*j

j= number of cups

For example, for 15 cups:

A= 20 + 0.75*15

A= $31.25

they would have to work 32 hours.
