D. How could you find the cost for 5 pounds of cheese without finding the cost per pound? Type your answer in the bo

Step-by-step explanation:

Given

cost of  2.5 pounds of cheese is $5.60.

To get the cost of one pound, we will use the equality postulate:

2.5 pounds = $5.60

1 pound = $x

cross multiply;

2.5x = 5.60

x = 5.60/2.5

x = $2.24

Hence one pound of cheese will cost $2.24

b) If Mrs. Peterson bought 4.75 pounds of cheese, to get the amount she paid, we will say:

1 pound = $2.24

4.75pounds = y

cross multiply

1*y = 2.24 * 4.75

y = $10.64

Hence the cost of 4.75pounds is $10.64

c) To find the cost of 5 pounds, we can use the fact that 2.5 pounds of cheese cost $5.60;

hence 2.5 pounds = $5.60

5 pounds  z

cross multiply

2.5z = 5*5.60

z = 5*5.60/2.5

z = 2*5.60

z = $11.2

Hence the cost of 5 pounds of cheese is $11.2
