Answer:

$570

Step-by-step explanation:

If she marks up the sofa for 90%, she will change the price to 760$

Now, 25% of 760$ is 190$. So, we subtract 190 from 760 and get 570$

Hope this helped, and have a good one!

Aaron wants to mulch his garden. His garden is x^2+18x+81 ft^2 One bag of mulch covers x^2-81 ft^2 . Divide the expressions and

blsea [12.9K]

Answer:

Step-by-step explanation:

Given

Garden: $x^2+18x+81$

One Bag: $x^2 - 81$

Requires

Determine the number of bags to cover the whole garden

This is calculated as thus;

$Bags = \frac{x^2+18x+81}{x^2 - 81}$

Expand the numerator

$Bags = \frac{x^2+9x+9x+81}{x^2 - 81}$

$Bags = \frac{x(x+9)+9(x+9)}{x^2 - 81}$

$Bags = \frac{(x+9)(x+9)}{x^2 - 81}$

Express 81 as 9²

$Bags = \frac{(x+9)(x+9)}{x^2 - 9\²}$

Evaluate as difference of two squares

$Bags = \frac{(x+9)(x+9)}{(x - 9)(x+9)}$

$Bags = \frac{(x+9)}{(x - 9)}$

Hence, the number of bags is $Bags = \frac{(x+9)}{(x - 9)}$

Apples sell for $1.90 per pound, and bananas sell for $0.75 per pound. Troy bought some apples and some bananas. Together they w

olga_2 [115]

Answer:

C. 1.15p + 2.85 = 5.84

Step-by-step explanation:

The equation above is not one you'd start off with to represent this problem. It is an intermediate step in the solution.

You can get there by realizing that the number of pounds of bananas is 3.8-p. Then the cost of the bananas is ...

banana cost = 0.75·(3.8-p) = 2.85 - 0.75p

Of course, the cost of apples is 1.90p. The total cost is then ...

apple cost + banana cost = total cost

1.90p + (2.85 -0.75p) = 5.84

Simplifying, this becomes ...

1.15p + 2.85 = 5.84 . . . . . . . . . . . . matches selection C
