Answer:

She shouldn't tip at all since that's a ridiculous concept

Step-by-step explanation:

common sense

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 = price + 0.1*price

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>

Citrus2011 [14]

Answer:

(x, y) → (x - 3, y + 5 )

Step-by-step explanation:

A shift of 3 units to the left means subtract 3 from the original x- coordinate.

A shift of 5 units up means add 5 to the original y- coordinate.

Thus the rule representing the translation is

(x, y ) → (x - 3, y + 5 )

An ounce of milk contains 20 milligrams of calcium and 60 micrograms of vitamin A.
vova2212 [387]

Answer:

10 ounces of milk and 50 ounces of orange juice

Step-by-step explanation:

Let the amount of milk be x ounces and the amount of orange juice be y ounces.

1. An ounce of milk contains 20 milligrams of calcium and 60 micrograms of vitamin A. Then x ounces of milk contain 20x milligrams of calcium and 60x micrograms of vitamin A.

2. An ounce of orange juice contains 40 milligrams of calcium and 10 micrograms of vitamin A. Then y ounces of orange juice contain 40y milligrams of calcium and 10y micrograms of vitamin A.

<u>Calcium:</u>

20x milligrams in milk

40y milligrams in orange juice

2,200 milligrams in total

Hence,

20x+40y=2,200

<u>Vitamin A:</u>

60x micrograms in milk

10y micrograms in orange juice

1,100 micrograms in total

Hence,

60x+10y=1,100

Solve the system of two equations:

\left\{\begin{array}{l}20x+40y=2,200\\ \\60x+10y=1,100\end{array}\right.

Divide each equation by 10:

\left\{\begin{array}{l}2x+4y=220\\ \\6x+y=110\end{array}\right.

From the second equation:

y=110-6x

Substitute it into the first equation:

2x+4(110-6x)=220\\ \\2x+440-24x=220\\ \\2x-24x=220-440\\ \\-22x=-220\\ \\22x=220\\ \\x=10\\ \\y=110-6\cdot 10=110-60=50
