Question

Store is selling Snapple’s for 1.75 and monsters for 2.50.yesterday their revenue was 147.75 and they sold 3 more monsters how many of each?

Answer 1

The number of Snapple’s sold = 33

The number of monsters sold = 36

Explanation:

Let us assume , the number of Snapple’s sold = m

So, the number of monsters sold = Number of Snapple’s + 3 = m + 3

Now, the cost of 1 Snapple’s = $1.75

So, the cost of m Snapple’s = m x ( cost of 1 Snapple’s) = m x ($1.75)

= 1.75 m

Now, the cost of 1 monster = $2.50

So, the cost of (m +3) monsters = (m + 3 ) x ( cost of 1 monsters)

= (m+3) x ($2.50) = 2.5 m + 7.5

So, total cost of ( m Snapple’s + (m +3) monsters) = 1.75 m + 2.5 m + 7.5

= 4.25 m + 7.5

Also, the total revenue generated = $147.75

⇒ 4.25 m + 7.5 = $147.75

or, 4.25 m = 147.75 - 7.5 = 140.25

so, m = 140.25/4.25 = 33

Hence, the number of Snapple’s sold = m = 33

And, the number of monsters sold = m + 3 = 33 + 3 = 36
