Question

What is 44 markers cost $7.04 dollar 7 markers

Which equation would help determine the cost of 777 markers?

Answer 1

4/7=$7.04/x

Explanation:

We know the cost of 4 markers. We want to know the cost of 7 markers. We can write the numbers of markers as a proportion:

4/7

​

We know 4 markers costs $7.04. We can let x represent the unknown cost of 7 markers. The proportion of these costs can be expressed as:

$7.04/x

​

The cost changes along with the number of markers purchased, and so the two proportions are equivalent.

4/7 = $7.04/x

Answer 2

x = Cost of 777 markers

x = 777 * 0.16 or x/777 = 0.16 or x/0.16 = 777

Explanation:

1. Let's review the information given to us to answer the question correctly:

Cost of 44 markers = $ 7.04

Cost of a marker = 7.04/44 = $ 0.16

2. Which equation would help determine the cost of 777 markers?

x = Cost of 777 markers

x = 777 * 0.16

or

x/777 = 0.16

or

x/0.16 = 777
