How much did Mia save up?

Question

Mia saved up some money for shopping. Her mom gave her $150 more.

At a shop, Mia spent $80 on a bag and half of the remaining money on a pair of shoes.

She was then left with $55. How much did Mia save up?

Answer 1

 

 

X is the amount saved

 

X+150 before shopping

 

X + 150 - 80 = X + 70 after buying the bag

 

1/2(X+70) is the price of the shoes

 

(X+70) - 1/2(X+70) = 55

 

1/2(X+70) = 55

 

X+70 = 110

 

X = 40

 

She saved 40.

Her mom gave her 150 more, so 190.

80 spent on the bag, so 110.

Half of that on the shoes, so 55.

 

She saved $40
