Handy Dandy Grocery is having a sale this week. If you buy a 5−pound bag of apples for the regular price, you can get another ba
Elis [28]

Answer:

To get the discount for the 5 pound bag of apples, we must first note the following:

The original price of the apples, which in this case it is 2.99

Also we must note the sale price for the apples which is 1.59

to get the discount for apples we must then create an equation based on the above information,

Discount for A= original price -sale price

Discount for A=2.99-1.59

Discount for A=1.40

Part 1 Answer is 1.40 which is the discount for apples at Handy Dandy Grocery.

Part 2

To get the discount for oranges we follow the same steps.

Discount for R= Original price for R -sale price for R

Discount for R=3.99-2.59

Discount for R=1.40

conclusion, for both part one and part two we can derive a formula based on the apples and orange and say discount in both cases is arrived by the following:

D=Op-Sp. ( d= discount, Or= original price, Sp= sale price.)

Product is -8 and sum is 2.<br> What are the two numbers
anygoal [31]

Step-by-step explanation:

Let the two numbers be x and y.

\therefore \: xy =  - 8...(1) \\  and \\ x + y = 2 \\  \\  \therefore \:x = 2 - y...(2)

From equations (1) & (2)

(2-y)y=-8\\\therefore \: 2y - y^2 = - 8\\\\\therefore \:y^2 - 2y-8=0\\\\\therefore \:y^2 - 4y+2y-8=0\\\\\therefore \:y(y - 4)+2(y-4)=0\\\\\therefore \:(y+2)(y - 4)=0\\\\\therefore \:(y+2)=0\:\: or\:\:(y - 4)=0\\\\\therefore \:y=-2\:\: or\:\:y =4\\\\    When \:\: y = - 2\implies x = 4\\\\When \:\: y = 4\implies x = - 2\\

Thus, the two numbers are (4, - 2) or (-2, 4).

Why is a financial plan important?????
mafiozo [28]
Without a financial plan, you can end up having a lot of debt. You also may not think about saving money for future expenses or how much you may need. Financial plans are very important for your future.

A desk is on sale for 629$ which is 85% of the regular price. what is the regular price?
garik1379 [7]

Answer:

$740.00

Step-by-step explanation:

85% of x is 629

Translate into algebra. Use a decimal in place of the percent:

.85x = 629

Divide by .85

x = 740

This answer makes sense because the regular price should be a little higher than the sale price. If they are paying 85% they're only getting 15% off.

Check:

740×.85 = 629
