Answer is x = 68 and y = 55

Let’s assume the two numbers are x and y

X + y = 123 — (1)

X + 5y = 343 — (2)

Write (1) in terms of x

X = 123 - y — (3)

Use in (2)

123 - y + 5y = 343

Rearrange to have only y terms on the right.

-y +5y = 343 - 123

4y = 220

y = 220/4 = 55

Found y = 55

Use y = 55 in (3)

X = 123 - 55 = 68

Found x = 68

Which line is a linear model for the data? ​
mestny [16]
The bottom right.
The line best fit is usually the line that follows the trend of dots in the scatter plot. In the other 3, you can tell that there seems to be no trend between either the line or the dots.
The bottom right one has a line pretty much right through the middle of the scattered dots and follows the trend.

The cost of a coffee maker is $76.70 the markup is 20% of the cost. What is the selling price of the coffee maker?
Dmitrij [34]

Answer: The selling price of the coffee maker is $92.04

If the original cost is $76.70 but the company wants to make profit from the product, meaning they want to sell it higher than what they purchased it for in order to gain money, then you add the markup cost to the original cost (20%).

$76.70 + 20% of $76.70

=$76.70 + $15.34

=$92.04 selling price of coffee maker.
