Answer:
Step-by-step explanation:
cost of playing x games at Adams = 7.50 + 0.45x
cost of playing x games at Jims = 1.25x
1.25x = 7.50 + 0.45x
1.25-0.45x = 7.50
0.80x = 7.50
x = 7.50/0.80 = 9.375 , but x must be an integer.
The cost is never the same. When x ≤ 9, Adams costs more. When x ≥ 10, Jims costs more.
168/3 = 56
<em>Therefore, Chad is driving the car in 56 mph.</em>
672/56 = 12
<em>Therefore, Chad drives 672 miles in 12 hours.</em>
308/11 = 28
<em>Therefore, Chad drives 28 miles per gallon of gas.</em>
672/28 = 24
<em>Therefore, Chad uses 24 gallons of gas to drive 672 miles.</em>
