Answer:
7.00
Step-by-step explanation:
discount = original price *20%
final price = original price - discount
Substituting the equation for discount
final price = original price - original price*20%
Factoring out the original price
final price = original price (1-20%)
Changing to decimal form and putting the final price
5.60 = original price (1-.2)
5.60 = original price (.8)
Divide by each side by .8
5.6/.8 = original price (.8)/.8
7 = original price

778 mile x ? hours = 50 miles per hours
Therefore,
778 miles /50 mph = 15.56 hours

933.6 minutes to the nearest minute is 934 minutes
