Answer:
One cup of coffee is $3.25
Step-by-step explanation:
Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut
2c + 4d = 10.5
c + 5d = 8.25
Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4
-10c - 20d = -52.5
4c + 20d = 33
Add them together and solve for c
-6c = -19.5
c = 3.25
So, a cup of coffee is $3.25

Answer:
14
Step-by-step explanation:
Replace with the values
15-1/2(2) = 15-1 = 14
1 foot = 12 inches
125 feet = 1,500 inches
60 feet = 720 inches
1,500 * 720 * 6 =
6,480,000 inches or 540,000 feet
It would be Y=2 as it's a horizontal line at y=2
