]A cell phone company charges $50 for the phone plus a monthly service charge of $30. The equation below describes the total cost y after x months. y = 30x + 50 Which is true of the relationship between x and y?

$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
