Trina is purchasing a new bike. the store is having a 20% off sale, and she has a 10% coupon. the original price of the bike is $89.75. what is the final price?

We know the original price of the bike:

price_original=$89.75

In order to calculate the final price, we should calculate the following: original price-sale-coupon

The sale is 20%, which means: sale=20/100*$89.75=0.2*$89.75=17.95

The coupon is 10%, which means: coupon=10/100*$89.75=0.1*$89.75=8.975

The final price is: price_final=$89.75-17.95-8.975=$62.825

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
