Which of the following expressions could be used to find the sale price of an item that costs d dollars if it is on sale for 30%

Elenna [48]

Greetings!

An item at full price is 100%, or by using the percentage formula: $(\frac{percentage}{100})$

If something is at 30% off, that means it is 70% of the original price (because minus the percentage from the 100%)

So by substituting the numbers into the percentage formula you end up with:

$(\frac{70}{100})$ which is 0.7

So your answer would be D, 0.7!

Hope this helps!

What’s the solution to this equation 2+x=7/8x-15

Nostrana [21]

Answer:x=−136

Step-by-step explanation: Step 1: Simplify both sides of the equation.

2+x=

x−15

2+x=

x+−15

x+2=

x−15

Step 2: Subtract 7/8x from both sides.

x+2−

x−15−

x+2=−15

Step 3: Subtract 2 from both sides.

x+2−2=−15−2

x=−17

Step 4: Multiply both sides by 8.

8*(

x)=(8)*(−17)
