Using the distributive property, you can distribute the 7 to y and -4. In other words, multiply the number outside of the parenthesis by each of the numbers in the parentheis. 
7*y+7*-4
=7y-28

To find an equivalent expression to this, use the distributive property.
The distributive property means to multiply the term outside the parentheses by each term on the inside.

7 • y = 7y
7 • -4 = -28
It's a negative 4 since it has a minus sign in front of it.

7y - 28 is what we get from this.
This can not be simplified further so it is the final answer.

Answer:
7y - 28

Hope this helps!

you are purchasing four items and you want to calculate the tax. The items cost 2.50, 8.75, 3.00, and 10.25. The tax rate is 6%.
vredina [299]
In the question it is already given that 4 items are being purchased and their individual rates are also given. the percentage of tax that needs to be paid is also given. To find the total amount of tax that has to be paid, you can either calculate the taxes on individual items and then add them or you can add the total amount required for the 4 items and then calculate the tax. Both will yield the same result but the second process is easier.
Cost of all the 4 items purchased = (2.50 + 8.75 + 3.00 + 10.25)
                                                       = 24.50
Percentage of tax that needs to be paid = 6%
Amount of tax that needs to be paid = (6/100) * 24.50
                                                           = 147/100
                                                           = 1.47
So the amount of tax that needs to be paid is 1.47.

To own and operate a poster printer, it costs $250 for the printer and an additional $0.20 per poster for ink. To print out post
NARA [144]

Answer:

312.5

Step-by-step explanation:

Since it is $250 plus 20 cents per poster, the equation is 0.20p+250. It is $1 per poster at store and you want to know when the cost is going to be the same so you set them equal to each other.

0.20p+250=p

250=0.80p

312.5=p
