Both are correct

Step-by-step explanation:

A store is having a 20% off sale. Micheal says that he can find the sale price of an item that has a regular price of "p" by evaluating the expression 0.8"p". Susan says that she can find the sale price for the same item by evaluating the expression "p"-0.2"p"

Store is having 20% off sale. Discount is 20%

LEt the regular price is 'p'

The discount price is 20% of p that is 0.2p

Sale price is original price - discount price

that is p - 0.2p . So Suna is correct

p - 0.2 p = 1p- 0.2p = 0.8p

So Michel is also correct

Hence, Both are correct

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!
