Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of , so the snow melted in x hours will be
.
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:
To find the depth of snow after 3 hours we will substitute in our expression.
Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.
Answer:
Step-by-step explanation:
500m = profit on mid-sized cars
750s = profit on SUVs
500m + 750s = total profit
You have two conditions:
(1) 500m + 750s ≥ 3500
(2) m ≥ 2s
Let s = 2
Check condition (1)
500m + 750 × 2 ≥ 3500
500m + 1500 ≥ 3500
500m ≥ 2000
m ≥ 4
Check condition (2)
(2) m ≥ 2 × 2
m ≥ 4
Check:
500 × 4 + 750 × 2 ≥ 3500 4 ≥ 2 × 2
2000 + 1500 ≥ 3500 4 ≥ 4
3500 ≥ 3500
OK.
