Rosita paid$27.08, including tax , for her family to eat dinner at a restaurant. She wants to tip a whole dollar amount that is
Bumek [7]

A <u>reasonable tip </u>would be $5.00

Rosita paid $27.08 an wants to tip a whole dollar <u>closest to 20%. </u>

The first step is therefore to find out 20% of $27.08.

= 20% x 27.08

= $5.42

The closest whole dollar depends on the first decimal point.

If it is 5 and above, the tip would be $5 as we would round down.

If it is 4 and below, the tip would be $6 as we would round up.

The<u> first decimal </u>is 4 so we would round down to $5.00

The tip would therefore be $5.00

Answer:

1. X axis, 8, 3

2. Y axis, 4,-9

Step-by-step explanation:

The rule of reflections that the place opposite of the axis is negative so:

The rule for x-axis reflection is (x,-y)

The rule for y-axis is (-x,y)

For the first one, x has remained the same, so that means it’s a x-axis reflection.

So change -3 to 3

Same for the next one.

-9 is not changed so that means it’s a y-axis reflection.

And the point is 4,-9
