Answer:
F(8,6)
Step-by-step explanation:
(x₁,x₂) --> E (-7, 2)
F(x₂,y₂)
Midpoint M(0.5 , 4)
Midpoint = 
Compare x,coordinates and y-coordinates,
-7 + x₂ = 0.5*2 ; 2+y₂ = 4*2
-7+ x₂ = 1 ; 2 +y₂ = 8
x₂ = 1+ 7 ; y₂ = 8 - 2
x₂ = 8 ; y₂ = 6
F(8,6)
18+4

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP
The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = <u>20</u>
now we need 20% of that so that's
20 * 0.2 = <u>4</u>
If she's simple-minded enough to tip that would amount to <u>$4</u>
Let p = the number of pennies
let q = the number of quarters
p + q = 23
0.01p + 0.25q = 3.11
