At a dinner, one meal cost $22 and a sales tax of $1.87 was added to the bill.

Answers

Answer:

5.61; 8.5 %

Step-by-step explanation:

Tax = $1.87 per $22 meal

For a $66 meal,

Tax = 66 × 1.87/22

Tax = 3 × 1.87

Tax = $5.61

=====

Tax rate = 1.87/22 × 100

Tax rate = 0.085 × 100

Tax rate = 8.5 %

Q#1: Amanda and Lisa are playing games at the arcade. Amanda started with $15, and the machine she is playing costs $0.75 per game. Lisa started with $13, and her machine costs $0.50 per game. After how many games will the two girls have the same amount of money remaining?
Q#2:The Lone Star Shipping Company charges $14 plus $2 a pound to ship an overnight package. Discount Shipping Company charges $20 plus $1.50 a pound to ship an overnight package. For what weight is the charge the same for the two companies?

Answers

Let D = the amount of money Deanna has after x games.

We know Deanna started with $15 and she spends 0.75 per game, so we can make the following equation:
D = 15 - 0.75x

Let L = the amount of money Lisa has after x games.

We know Lisa started with $13 and she spends 0.50 per game, so we can make the following equation:
L = 13 - 0.5x

The question is asking how many games need to be played for L and D to be equal, so just equate L and D and solve for x:

D = L
15 - 0.75x = 13 - 0.5x
15 - 13 = -0.5x + 0.75x
2 = 0.25x
2 = (1/4)x
8 = x

Therefore they need to play 8 games each to have the same amount of money.

Answer: For question one its 8

Step-by-step explanation: Let A be the variable for Amanda! The amount of money she has for x amount of time. We know that lisa has $13 and she is spending .50 every game. The equation for this would be L=13-0.5x. SO to solve this problem of when they both will have the same amount of money use the equation. 15- 0.75x=13 - 0.5x then you will switch the equation around. So the next step would look like 15-13= -0.5x + 0.75x! Then you'll get 2=0.25x change that to a fraction and you'll get 1/4 and 8=x!

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^
