Trisha and her three sisters decide to purchase their mom a Christmas gift. they decide that everyone will contribute equal amount, up to $60 per person. Write and solve an inequality to determine how much money will the sisters spend on their mom for Christmas.​

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)  

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
