Question

A store sells bottles of water for $1.50 each. During the first hour the store was open, x bottles of water were sold. During the

second hour, the store sold 3 fewer bottles of water than it sold during the first hour. During the third hour, it sold three times as
many bottles of water as it sold during the second hour. The store was paid a total of $117.00 for bottles of water sold during these
three hours. The equation shown below represents these sales.
1.5x + 1.5(x - 3) + 1.5.3(x - 3) = 117
How much money was the store paid for bottles of water sold during the second hour it was open?
(A) $15.00
(B) $22.50
(C) $27.00
(D) $67.50

Answer 1

The answer is $22.50

Explanation:

Answer 2

Answer: 22.50$

Explanation:

1.5x+1.5(x-3)+1.5*3(x-3)=117

1.5x+1.5x-4.5+1.5(3x-9)=117

3x-4.5+4.5x-13.5=117

7.5x-18=117

7.5x=135

x=135/7.5

x=18

hour 2

1.5(18-3)=

1.5*15= 22.5$
