Answer:
y=8.50x
Where y is the total cost and x is the number of cars washed
Step-by-step explanation:
Divide 93.50 by 11 and you get 8.50. When you divide 195.50 by 23, you still get 8.50. Therefore, the cost of the car wash is 8.50 per car.
Answer:
8 chicken, 4 beef
Step-by-step explanation:
No. of chicken: x
No. of beef: y
x + y = 12
x = 12 - y
10x + 14y = 136
10(12 - y) + 14y = 136
120 - 10y + 14y = 136
4y = 16
y = 4
x = 12 - 4
x = 8
