the supply store sells 4 pencils for every 5 pens the store sold 28 pencils yesterday how many pens did it sell

Answer 1

Let's assume the number of pens the store sold yesterday is represented by x.

According to the given information, the store sold 4 pencils for every 5 pens. This can be written as:
4/5 = 28/x

Cross-multiplying, we get:
4x = 5 * 28
4x = 140

Dividing both sides by 4, we find:
x = 35

Therefore, the store sold 35 pens yesterday.
