Question

Tiana uses the equation c=21h to figure out the total amount,c, she should charge a customer for babysitting for h hours.

Answer 1

21 x number of hours = total amount

Explanation:

Replace h with the number of hours in the equation 21h = c

Multiply the number of hours with 21 to get the cost.

Answer 2

I can't provide an answer due to the fact that it only states the equation and not the number of hours Tiana babysits for, but it's quite simple!

Multiply the number of hours babysitting (c) by 21.
