Rani has at most $20 to spend on a canoe rental. To rent a canoe $12.To use the canoe cost $3 an hour. Write an inequality that
Julli [10]

Answer:

Rani can use the rented canoe for  h\leq 2\frac{2}{3}  hours.

Step-by-step explanation:

Given:

Rani has at most $20 to spend on a canoe rental.

To rent a canoe $12.To use the canoe cost $3 an hour.

The number of hours is h.

Now, to find h the number of hours rani can use the rented canoe.

Total money Rani has at most to spend = $20.

The rent of a canoe = $12.

The cost of using canoe per hour = $3.

<em><u>According to question:</u></em>

Now, to find the number of hours rani can use the rented canoe:

3h+12\leq 20

<em>Subtracting both sides by 12 we get:</em>

<em />3h\leq 8<em />

<em>Dividing both sides by 3 we get:</em>

<em />h\leq \frac{8}{3}<em />

<em />h\leq 2\frac{2}{3}<em />

Therefore, Rani can use the rented canoe for  h\leq 2\frac{2}{3} hours.
