Answer:
$2500
Step-by-step explanation:
Given that:
Darcy's weekly earning = $982 plus 18% commission on food sales
Harper's weekly earning = $807 plus 25% commision
amount of food sales will result in Darcy and Harper earning the same amount for the week
Let amount of food sales = f
Darcy's earning = Harper's earning
(982 + 18%*f) = (807 + 25% * f)
(982 + 0.18f) = (807 + 0.25f)
982 + 0.18f = 807 + 0.25f
982 - 807 = 0.25f - 0.18f
175 = 0.07f
f = 175 / 0.07
f = 2500
Hence amount of food sales that will result in both Darcy and Harper earning the same amount = $2500
25 x .15 = 3.75
25 - 3.75 = 21.25
21.25 x .20 = 4.25
21.25 - 4.25 = $17 total
