Question

Rachel gets $4 a week for doing the dishes. She wants to buy a toy that costs $5. How many weeks does she needs to do the dishes

Answer 1

She needs to wash the dishes 2 times a week.

Explanation:

$5 is what we are trying to get,

$4 is what she makes per week

4+x=5, so x is $1, but Rachel can't just make one dollar, so you round and find that 2 weeks is the most suitable.
