Maria takes 25% of $26.50 and subtracts that amount from the normal price. she takes 10% of the discounted selling price and adds it back to find the purchase amount

Sorry I don't know about edwin's but I do know maria's

Step-by-step explanation:

What Maria did:

1.25% of $26.50 = 6.625 or 0.25 x 26.50 = 6.625

2. 6.625 - 26.50 = 19.875 or 19.88

3. 10% x 19.88 = 1.988 or 2.00

4. 2.00 + 19.88 = 21.88

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
