Which statement correctly summarizes her savings?



Samantha will save $45.00 because the two sales will combine for 75% off the original cost.

Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction.

Samantha will save $22.50 because she must first find the 25% sale price before taking the extra 50% reduction.

Answer 1

also she could save 15.00 but I don't think that's right

Answer 2

ok ill help you, so whats confusing you

Answer 3

okay so first you need to see how much the dress is 25% off and then 50% of that so

60*(1-0.25) *0.5 =?
^---50% off
^--25% off off

Answer 4

that is the new price of the dress

Answer 5

does it make sense??
25% off means u are left with 75% of the price

soo
60*0.75 = price after the 25% off

60*0.75 * 0.5 = price after the 50% off is applied to the 25% off price

Answer 6

60*0.75 * 0.5 = price after the 50% off is applied to the 25% off price
60*0.75 * 0.5 = 22.5

therefore she paid 22.5 for the new dress when it originally was 60
so
she saved
60-22.5=37.5
