The number of small boxes is 9 and the number of large boxes is 3
Step-by-step explanation:
Let x be the number of large boxes.
The camp bought 3 times as many small boxes as large boxes, then the number of small boxes is 3x.

Answer:
189
Step-by-step explanation:
Since the series is geometric with common ratio r, then
r = 6 ÷ 3 = 2
The terms in the series are twice the previous term, that is the series is
3 + 6 + 12 + 24 + 48 + 96 ← summing the terms gives
sum = 189
The equation would be y=2x+3. To find any x-value just plug in the y and solve for x. To find any y value just plug in the x and solve for y
