Question

The manufacturing cost of a cell phone was $136. Sellers first marked up the cost by 25 percent. Sales were poor, so sellers decreased the markup to 17 percent. Calculate the old and new selling prices. selling price = original cost + markup value

Answer 1

Answer: Old selling price is $170 and new selling price is $159.12

Step-by-step explanation:

Given Cost Price , CP=$136

For old selling price

Selling Price(SP) = Cost Price(CP) + Markup Value(MV)

Now MV= $MV=\frac{CP\times 25}{100}=\ \frac{136\times 25}{100}=\ 34$

=>SP = $136+$34=$170

Thus old selling price is $170

For new selling price

New Markup Value(NMV) = $\frac{CP\times 17}{100}=\ \frac{136\times 17}{100}=\ 23.12$

=>New Selling Price , NSP= $136+$23.12=$159.12

Thus new selling price is $159.12

Answer 2

Answer: old price = $170 and new price = $159.12

Step-by-step explanation:

Given : The manufacturing cost of a cell phone was $136.

Sellers first marked up the cost by 25 percent.

(25% can be written as 0.25 ).

Then , the old price : Cost price+0.25  x cost price

=$136+0.25($136)=$170

Hence, the old price = $170

Sales were poor, so sellers decreased the markup to 17 percent.

(17% can be written as 0.17).

Then , the new price :  Cost price+0.25  x cost price

=$136-0.17($136)=$159.12

Hence, the new price = $159.12
