3. Mike bought 8 pairs of socks and a Tshirt. his bill was $31.50. Determine the price for each pair of socks if the cost of the Tshirt was 7.50

1. X = The # of trees planted in March.
2x + 3=The # of trees planted in April.
Eq: 2x + 3 = 73.
2. X = The # of minutes used.
C = the total charges.
Eq: C = 0.1x + 4.99.
3. X = Cost of each pair of socks.
C = Total cost.
Eq: C = 8x + 7.50.
