Three pounds of raisins and 4 pounds of corn flakes are used to make a cereal of 7 pounds.
Thus we have, 3 * $1.11 + 4 *$0.90 = $6.93 (for 7 pounds of cereals) Price of 1 pound of cereal =$6.93/7 = $0.99 To make a profit of$0.21 per pound the selling price of the cereal per pound must be $0.99 +$0.21 = $1.20 Hence option D is correct.

To make a profit of $0.21, the price grocer should charge =$ 0.99 + $0.21 =$ 1.20

B. $1.00 C.$1.07
D. $1.20 E.$1.21

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

Solution

Given:

• Three pounds of raisins and 4 pounds of corn flakes are used to make a large bag of breakfast cereal
• Raisins cost $1.11 per pound and flakes cost$0.90 per pound.

To find:

• The selling price per pound of the cereal to make a profit of \$0.21 per pound.

Approach and Working:

• Cost Price of 3 pounds of raisins= 3*1.11= 3.33
• Cost Price of 4 pounds of corn flakes = 4 * 0.90= 3.60

Hence, Cost price of 7-pound cereal meal= 3.33+3.60= 6.93.
• Thus, selling price = 6.93+ 0.21*7
• Selling price per pound= $$\frac{6.93}{7}+0.21$$= 0.99+0.21= 1.20

Hence, the correct answer is option D.
