Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets
Answer:
936
Step-by-step explanation:
First calculate the volume of each container. to calculate volume, multiply the length * width * height.
For Container A, the volume is 13 * 19 * 25 = 6175 inches.
For Container B, the volume is 13 * 13 * 31 = 5239 inches.
6175 - 5239 = 936 so the volume Container A is 936 cubic inches greater than the volume of Container B.
