Question

At the greenhouse of salad, you can get a one dollar coupon for every 3 salads. What is the least number of salads you could buy to get 10 dollars in coupons?

Answer 1

30 salads.

Explanation:

We have been at the greenhouse of salad, you can get a one dollar coupon for every 3 salads. We are asked to find the least number of salads you could buy to get 10 dollars in coupons.

We will use proportions to solve our given problem as:

`\frac{\text{Number of Salads}}{\text{Coupons}}=(3)/(\$1)`

Now we will substitute $10 for coupons and solve for number of salads as:

`\frac{\text{Number of Salads}}{\$10}=(3)/(\$1)`

`\frac{\text{Number of Salads}}{\$10}*\$10 =(3)/(\$1)*\$10`

`\text{Number of Salads} =3*10`

`\text{Number of Salads} =30`

Therefore, you can get $10 coupons after buying 30 salads.
