A computer is priced $500 but is on sale for 30% off. What is the sale price of the computer

$350

Step-by-step explanation:

if the sale is 30% we have to find what is 30% of 500 so we can subtracted from what we pay .

line up what you know:

$500 represents  100%

    $x represents  30 %

cross multiply

x*100 = 500* 30 ; divide both sides by 100

x= 500*30 /100 = 150

the sale price is 500-150= $350

$18 was the price of the t-shirt

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 .
