Question

(Ratios) Three bags of dog food cost $26.88, including tax. Jerry has $50.00. How many bags of dog food can Jerry buy?

Answer 1

Jerry can buy 5 bags of dog food from $50.00

Explanation:

Given that:

Cost of three bags = $26.88

Ratio of number of bags to cost = 3 : 26.88

Amount Jerry have = $50.00

Number of bags that can be bought = x

Ratio of number of bags to amount jerry have = x : 50.00

This is a direct proportion,

`3:26.88::x:50.00`

Product of mean = Product of extreme

26.88x = 3*50.00

26.88x=150.00

Dividing both sides by 26.88

`(26.88x)/(26.88)=(150.00)/(26.88)\\x=5.58`

Hence,

Jerry can buy 5 bags of dog food from $50.00
