Adams arcade charges an entrance fee of $7.50 and 0.45 per game. Jims jamming does not charge an entrance fee but the games are
$1.25 each. How many number of games must be played in order for the total cost of both arcades to be the same?
1 answer:
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.

Answer:
f(x) = 12x - 4
Step-by-step explanation:
f(x)= 20 + 12(x - 2)
Distribute
f(x) =20 +12x - 24
Combine like terms
f(x) = 12x+20-24
f(x) = 12x - 4
-8y = -4x + 16
Y = 4/8x - 2
