Answer:

The inequality is .5d + 1 ≤ 10, which would yield the result of d ≤ 18

Step-by-step explanation:

In order to find this, we need to model the equation. We know that the constant is 1, and the coefficient of the variable, which needs to be multiplied by d is .5.

.5d + 1

Now we also know that this has to be less than or equal to the 10 dollars we have

.5d + 1 ≤ 10

And then if we want we can solve.

.5d + 1 ≤ 10

.5d ≤ 9

d ≤ 18
