Find the surface area of the prism or pyramid. Round to the nearest whole number if necessary.

72

Step-by-step explanation:

(7*2)4=56

(4*2)2=16

56+16=72

I would say that the total surface area is 100mm^2.

Step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
