Question

I know this problem is change abs absolute & percent but just don’t know where to start

Answer 1

a)

32 oz jug cost costs $9

Let x be the cost of 44 oz of detergent. Then we have:

44/32 = x/9

x = 9*(44/32)

x = $12.38

b)

Since 44/32 = 1.375, the percent increase in the amount of detergent is given by (1.375 - 1) = 37.5%

c)

Since 32/44 = 0.7272..., the percent decrease in the amount of detergent is given by (1 - 0.7272) = 27.27%

d)

In this case, the new price of a 32 oz jug of Sudz is given by (32/44)*9 = $6.55
