It’s hard may anyone me answer this question

D. $53.76

Step-by-step explanation:

When calculating discounts and sales tax, you need to first change your percentages to decimals by dividing each by 100:

20%/100 = 0.2

5%/100 = 0.05

Since the shoes are at a 20% discount, you will only pay 80% of the original amount, or:  $64.00 x 0.8 = $51.20

However, you also need to pay a 5% sales tax, in addition to the sales price, so you can take the discounted amount and multiply:

$51.20 x 1.05 = $53.76 total cost

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
