Question

44 markers cost $7.04 Which equation would help determine the cost of 7 markers?

Answer 1

$ 1.12

Explanation:

Finding the cost

we can use cross multiplication

markers : cost

44 : 7.04

7 : x

x is used to find the cost of 7 markers

now cross multiply:

44x = 7*7.04

44x = 49.28

x = 49.28 / 44

x = $ 1.12

Answer 2

(7.04/44)*7

7*(7.04/44)

Explanation:

you have to find the cost of each individual marker:

$7.04/44= .16 (Checked it on a calculator)

then you multiply .16 by 7 because each marker costs 16 cence and you need to find the total cost of 7 markers so your equation should look like:

#1 way to write it: (7.04/44)*7

#2 way to write it: 7*(7.04/44)
