Question

Laura wants to rent a boat and spend less than $75. The boat costs $7 per hour, and Laura has a discount coupon for $9 off. What are the possible numbers of hours Laura could rent the boatUser t for the number of hours.Write your answer as an inequality solved for t.

Answer 1

We have the next given information:

- Laura wants to rent a boat and spend less than $75.

-The boat costs $7 per hour.

- Laura has a discount coupon for $9 off.

The symbol for "less than" is given by "<"

Let us set t for the number of hours. Then we can write the next inequality:

`7t-9<75`

Where the t variable depends on the number of hours. and we subtract the discount coupon.

Now, we need to solve it for t:

`\begin{gathered} 7t-9<75 \\ Solve\text{ for t:} \\ 7t<75+9 \\ 7t<84 \\ t<12 \end{gathered}`

She could rent the boat for less than 12 hours.

The answer as an inequality is t<12.
