# Solve the following word problems for the unknown. Round decimals to hundredths and percents to the nearest tenth when necessary.Last year the Tundra Corporation had sales of $343,500. If this year’s sales are forecast to be$415,700, what is the percent increase in sales?

To determine

To calculate: The percent increase in sales, if the sales of Tundra Corporation was $343,500 last year and the predicted sale of this year is$415,700.

Explanation

Given Information:

The sales of Tundra Corporation were $343,500 last year and the predicted sale of this year is$415,700.

Formula used:

Step1: Recognize the original amount and the new amount and find the difference between them.

Step2: Put the difference obtained in step 1 for the portion and the given original amount for the base in the rate formula, “R=PB”.

Step3: Solve the equation for rate and convert the answer obtained into percent.

Calculation:

The sales of Tundra Corporation were $343,500 last year and the predicted sale of this year is$415,700.

Here, Original amount is $343,500. New amount is$415,700.

Difference between the original and the new amount is,

$415,700$343,500=$72,200. Now, the value of base is B=$343,500 as base is the original amount and value of portion is P=\$72,200 as portion is the difference between the original and the new amount
