Marcy wants to buy a new dress that costs $56.77. She has been babysitting to earn the money to buy the dress. She makes $5.50 per hour babysitting and she babysat a total of 9.5
hours last week. How much more money does Marcy need?

she needs $4.52

Step-by-step explanation:

(9.5*5.50)+x=56.77

52.25+x=56.77

x=56.77-52.25

x=4.52

true

explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
