nearest penny. Show your work.

Answer 1

To find Conor's total cost using one of the expressions from part a, we need to choose a specific value for t between $12 and $13.

Let's choose t = $12.50.

Using the expression 1.08t + 0.15, we can substitute t = $12.50:

Total cost = 1.08 * 12.50 + 0.15
= 13.50 + 0.15
= $13.65

So Conor's total cost, rounded to the nearest penny, is $13.65.
