Final answer:
Elio will save $48.75 by saving 25% of his total earnings, which is $195, after walking 13 dogs at $15 each.
Step-by-step explanation:
The student is asking about how much money Elio will save after walking 13 dogs if he saves 25% of his earnings from his dog-walking business.
First, we need to calculate Elio's total earnings from walking 13 dogs at a rate of $15 per dog. Then, we will calculate 25% of that total to find out how much Elio saves.
Elio's total earnings: 13 dogs × $15/dog = $195
Elio's savings (25% of earnings): $195 × 0.25 = $48.75
After walking 13 dogs, Elio will save $48.75.
