Answer:
Step-by-step explanation:
Distance = 48 * 4
Distance = 192
~~~~~~~~~~~~~~~
3*50 = 150
192 - 150 = 42
42 MPH for the last hour
Let the price of paint be x and the price of brush be y
8x + 3y = 152.5 ------------ (1)
6x + 2y = 113 --------------- (2)
(1) x 2 :
16x + 6y =305 -------------(1a)
(2) x (3) :
18x + 6y = 339 -------------(2a)
(2a) - (1a) :
2x = 34
x = 17 ---------- sub into (2)
6(17) + 2y = 113
102 + 2y = 113
2y = 113 - 102
2y = 11
y = 5.5
x = $17, y = $5.50
Each gallon of paint costs $17 and each brush costs $5.50
