Lydia bought a shirt at 20% off it’s retail price of $40. she paid 5% tax on the price after the discount. how much did lydia pay for the shirt?

$33.60

Step-by-step explanation:

1. multiply the price (40) times 20% (.20)

    40*.20=8 - that's the amount of the discount

2. Subtract 8 from 40

    40-8=32 - that's the discounted price.

3. multiply 32 by 5% (0.05)

    32*.05 = 1.60 - that's the sales tax

4. add 32 + 1.60 = 33.60

3,000,540

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
