Question

a textbook store sold a combined total of 236 chemistry and math textbooks in a week. the number of chemistry textbooks sold was three times the number of math textbooks sold. how many textbooks of each type were sold? number of chemistry textbooks sold: number of math textbooks sold:

Explanation:

Step1: Set up variables

Let \( x \) be the number of math textbooks sold. Then the number of chemistry textbooks sold is \( 3x \).

Step2: Create equation

The total number of textbooks sold is \( x + 3x=236 \).
Simplify the left - hand side: \( 4x = 236 \).

Step3: Solve for \( x \)

Divide both sides by 4: \( x=\frac{236}{4}=59 \).

Step4: Find the number of chemistry textbooks

Since the number of chemistry textbooks is \( 3x \), substitute \( x = 59 \). So \( 3x=3\times59 = 177 \).

Answer:

Number of chemistry textbooks sold: \( 177 \)
Number of math textbooks sold: \( 59 \)
