To solve this problem, we need to determine the value of x, which represents the number of boxes of fireworks that Cherie has.
Let's break down the information given:
Number of boxes of fireworks Koby has: 2
Number of sparklers in each of Koby's boxes: 3
Number of whistlers in each of Koby's boxes: 5
Number of sparklers in Cherie's box: 8
Number of whistlers in Cherie's box: 9
Total number of fireworks: 33
We can set up the equation as follows:
(Number of boxes of fireworks Koby has * (Number of sparklers in each of Koby's boxes + Number of whistlers in each of Koby's boxes)) + (Number of sparklers in Cherie's box + Number of whistlers in Cherie's box) * Number of boxes of fireworks Cherie has = Total number of fireworks
(2 * (3 + 5)) + (8 + 9) * x = 33
Let's simplify and solve for x:
(2 * 8) + 17x = 33
16 + 17x = 33
To isolate x, we subtract 16 from both sides of the equation:
16 + 17x - 16 = 33 - 16
17x = 17
To solve for x, we divide both sides of the equation by 17:
x = 17 / 17
x = 1
The value of x is 1.
#### 1
The answer is: 1
