Answer:

1500-40%= 900

1500-25%= 1125

1500-10%=1350

640-25%= 480

640-10%=576

$640-5%=608

Step-by-step explanation:

In order to calculate this you just need to mutliply the cost of the products by the amount that is not in disscount, for example the 1500 product has a disscount of 25% that means that the final cost will be 75% so 1500+.75=1125 and taht would be the cost.

The same with all of the other prices,  you taje the original price and multiply it by the decimal final percentage price, and you get the final price.

What is the value of y in the equation 5x+2y=20, when x=0.3
Rasek [7]

5x+2y=20

Substitute 0.3 for x

5(0.3)+2y=20

Multiply 5 by 0.3

1.5+2y=20

Subtract 1.5 from both sides

2y=18.5

Divide 2 on both sides

Final Answer: y= 9.25
