Eva earns $16 for walking dogs for 4 hours. if eva charges at the same rate, how many hours will it take her to earn $32

8 hours

Step-by-step explanation:

Eva earns $16 dollars for every 4 hours of dog walking. We already know that half of 32 is 16, so we know that Eva just needs 16 more dollars to get to $32. If she makes $16 every 4 hours, and needs to make $16 more, she needs to work another 4 hours.
