Here is a prism with pentagonal base, and a view of just the base and prism. The height is 8 cm. What is the volume of the prism?

Whose mistake? can you give more details to what the question is asking?

$250 deductible means jane must pay the first $250 of her bill. so the insurance company paid = (80% of bill) - deductible = (0.8 x $2550) - $250 = $2040 - $250 = $1790 and jane's cost is = (bill) - (insurance payment) = $2550 - $1790 = $760
