Tom bought a pen for $60 and sold it to gain 20% on his cost price. How much money did he gain?

Solution: CP of the pen = $60.

Gain = 20%.

(SP-CP)*100/CP = Gain %

(SP-60)*100/60 = 20, or

SP-60 = 60*20/100 = 12

SP = 60+12 = $72.

Gain = $72-$60 = $12. Answer.

Step-by-step explanation:

403.2

Step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
