step-by-step explanation:

where is the question is there is a formula or is there not one

you start with 40 minutes and 8 people to paint a wall. then it asks how many minutes does it take 10 people to paint seven walls.

that means you start with division.

40÷8=5

now you have to multiply that by 10

10×5=50

now you want to multiply the amount of walls by number minutes.

50*7= 150 minutes or 2½hrs

hope this ! -john
