Question

Noah already has $10.50, and he earns $3 each time he runs an errand for his neighbor. Noah wants to know how many errands he needs to run to have at least $30

Answer 1

Answer: 7 errands

Explanation:

Noah wants to have at least $30. He however already has $10.50.

The amount that he needs is:

= 30 - 10.50

= $19.30

For every errand he runs, he makes $3. The number of errands needed to get to $30 is:

= 19.50/3

= 6.5

= 7 errands
