2- 60

2- $2.04

4- $1476

5- $77

Step-by-step explanation:

1- 6 x 3.80 = 22.8

22.8 + 3.10 = 25.90

2- 1 hour = 2 thirty minutes

15 x 4 = 60

3- 3.4 x .60 =$2.04

4- 6 x 3 = 18

18 x 12 = 216

15 x 7 = 105

105 x 12 = 1260

1260 + 216 = 1476

5- 5 x 14 = 70

70 + 7 = 77

3) 3.80*6+2.10 = $24.90

4) 15° in 30 mins, which means 30° in an hour. so in two hours. 2x30 = 60°
