Round trip travel: 2*15miles*$0.45/mile = $13.5
Equipment: $84 + $15.50 + $47 + $32 + $22 = $200.50
Tax = $200.50 * 5%/100 = 10.025
Lessons: $25*10 = $250
Total cost = 13.5 + 200.5 + 10.025 + 250 = $474.025
Answer:
45
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
3x+5x+4x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15
The smallest angle is 3x
3(15) = 45
