well, I think you mean what is y.

The Answer is

y = 5

Answer:

5

Step-by-step explanation:

X + 2y = 13

Since x = 3

3 + 2y = 13

2y = 13 - 3

2y = 10

Divide both sides by 2

Y = 5

A store pays $365.84 for a fountain. The store marks up the price by 10%.
Ann [662]

Answer:

The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

Step-by-step explanation:

Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:

365.84 x 10/100 = X

3,658.4 / 100 = X

36,584 = X

36.584 + 365.84 = 402.424

Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.
