Annah should get back 1.01 as her change
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)
Answer:
f(11) = 9
Step-by-step explanation:
f(x) = 1/4(5-x)^2
f(x) = 1/4 (5-11) ^2
f(11) = 1.25 - 2.75 ^2
f(11) = 9
