Ryan worked for 7 hours and earned $52.50. If this rate increased by 4%, what will he earn if he works for 8 hours?

$62.40

Step-by-step explanation:

7 hours of work: $52.50

1 hour of work:

$52.50 / 7 = $7.5

$7.5 per hour

If Ryan's rate increased by 4%, what would he earn per hour?

$7.5 * 1.04 = $7.8

New hourly wage: $7.8 per hour

For 8 hours of work:

$7.8 * 8 = $62.4 = $62.40

$62.40

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 %
