Answer:

\boxed{\sf r=10}

<h3><u>Step-by-step explanation:</u></h3>

\sf 4(2r+5)=10r

Expand: Use the Distributive Property to multiply 4 by 2r+5:

\longmapsto\sf 8r+20=10r

Subtract 20 from both sides:

\longmapsto\sf 8r+20-20=10r-20

\longmapsto\sf 8r=10r-20

Subtract 10r from both sides:

\longmapsto\sf 8r-10r=10r-20-10r

\longmapsto\sf -2r=-20

Divide both sides by -2:

\longmapsto\sf \cfrac{-2r}{-2}=\cfrac{-20}{-2}

\longmapsto\sf r=10

I buy a MP3 player for £40 in a sale where it was 20% off. What was the original price
natta225 [31]
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
