Emily spent 1/2 of her money at the grocery store. Then, she spent 1/2 of what was left at the baker. Next she spent 1/2 of what was left on a cd. She spent the remaining $6.00 on lunch. How much money did she start with ?
It’s 48. Just multiply 6 times 2, (12), then 12 times 2, (24), and 24 times 2, (48). I went to school and they said it was correct.
48
(1/2)x + (1/4)x + (1/8x) + 6 = x
(7/8)x + 6 = x
6 = (1/8)x
6 / (1/8) = x
6 * 8 = x
48 = x
