Answer:
The final bill will cost $1,250.
Step-by-step explanation:
1000(0.7) = 70
1000(0.18) = 180
1000 + 180 + 70 = 1250
Step-by-step explanation:
2x² + 8y = 121.5
x² - 8y = 121.5
Add the equations together to eliminate the y terms.
3x² = 243
x² = 81
x = 9
Volume of the shampoo bottle
V = πr²h
Substituting,
V = π(2 in)²(7 in) = 87.9 in³ ≈ 88 in³
Volume of the suitcase,
Convert all dimensions to inches by multiplying by 12.
length = 36 in ; width = 24 in ; height = 12 in
Multiply the given dimensions,
V = (36 in)(24 in)(12 in) = 10,368 in³
Dividing the two calculated values will give us an answer of 117.82 or approximately 117 bottles.
The mistake done is described in letter A because as much as possible we want to overestimate the volume of the shampoo as its value becomes the divisor.
