### Instruction:
Macey saves to buy herself a shirt that costs $3. She was able to save $1.50 already. How many weeks does she need to save for the remaining amount if she saves $0.50 per week?

### Response:
It costs $3 to buy the shirt
She has $1.50 saved up already
She needs to save $3 - $1.50 = $<<3-1.5=1.5>>1.50 more
She saves $0.50 per week
She needs to save $1.50 / $0.50 = <<1.5/0.5=3>>3 weeks
