<h3>
Answer: 50%</h3>
Work Shown:
change = new - old = 189-126 = 63
percent increase = (change/old)*100%
percent increase = (63/126)*100%
percent increase = (0.50)*100%
percent increase = 50%
50% of 126 = 0.50*126 = 63
126+63 = 189
The answer is confirmed.
Answer:
10 games
Step-by-step explanation:
Let C be cost and x be number of games
Arcade A: C = 5 + 0.6x
Arcade B: C = 7 + 0.4x
for both arcades to be the same price, Both C's must be equal, hence we equate the right side of both equations:
5 + 0.6x = 7 + 0.4x (subtract 5 fromboth sides)
0.6x = 7 + 0.4x - 5
0.6x = 2 + 0.4x (subtract 0.4x from both sides)
0.6x - 0.4x = 2
0.2x = 2 (divide both sides by 0.2)
x = 2 / (0.2)
x = 10
4*8
=24
24/2
=12
Perimeter is 12 units
