3 A store is having a sale. Each customer receives either a 15% discount on purchases
under $100 or a 20% discount on purchases of $100 or more. Kelly is purchasing some
clothes for $96.60 before the discount. She decides to buy the fewest packs of gum that
will increase her purchase to over $100. The price of each pack of gum is $0.79.
After the discount, how much less will Kelly pay by purchasing the clothes and the gum
instead of purchasing only the clothes? (Assume there is no sales tax to consider.)
A $1.05
B $1.67
C) $3.69
D) $3.87

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
