Question

Malik bought a pack of erasers for $3.50 and some pencils for $0.99 each. He paid a total of $10.43. Which equation can be used to find the number of pencils Andrew bought? \

Answer 1

The equation that can be used to find the number of pencils Andrew bought is:

x=(c-3.50)/0.99

Explanation:

With the information provided, you can say that the total amount paid would be equal to the price of the pack of erasers plus the price per pencil for the number of pencils purchased, which can be expressed as:

c=3.50+0.99x, where:

c is the total cost

x is he number of pencils purchased

Now, you can solve for x in order to find the equation to calculate the number of pencils Andrew bought:

c-3.50=0.99x

x=(c-3.50)/0.99

According to this, the answer is that the equation that can be used to find the number of pencils Andrew bought is:

x=(c-3.50)/0.99
