Ahardware store sells a 5-pound box of nails for $16.80. the store is having a 20 percent off sale on all merchandise. what is the sale price of one 5-pound box of nails?

$13.44

Step-by-step explanation:

A percent is a portion of 100. If $16.80 is 100% of the price, and we receive 20% off then we pay 80% of the price. 100%-20%=80%. We find the new price by multiplying 16.80 by the percent as a decimal. 80% is 0.80.

16.80(0.80)=$13.44.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
