C. $1.07 D.$1.20
E. $1.21 The OA is D. Please, can any expert explain this PS question for me? I tried to solve it but I can't get the correct answer. I need your help. Thanks. Cost of three pounds of raisins: 3 * 1.11 = 3.33 Cost of four pounds of cornflakes: 4 * .90 . = 3.60 Total cost of 7 pounds of cereal = 3.33 + 3.60 = 6.93 Cost per pound = 6.93/7 = .$99

To make a profit of $.21, they'd have to charge .99 + .21 =$1.20. The answer is D

First, we can determine the total cost to the grocer:

Cost for raisins = 3 x 1.11 = $3.33 Cost for corn flakes = 4 x 0.90 =$3.60

Total cost to grocer = $6.93 Cost per pound = 6.93/7 =$0.99

Since the grocer wants to make a profit of $0.21 per pound, he must charge: 0.99 + 0.21 =$1.20
