Amir has spent the last three months saving money for a $1,400 computer in his local electronics store. So far he has saved $1,2
00. Today, he receives an email saying that all computers in the store are 25% off for one day only. If the sales tax charged at the counter is 7%, does Alex have enough money to purchase the computer today?
25% off of $1400 equal: 1400 + .25 = 350, so 1400 - 350 = 1050 So now the computer with 25 % off is $1050. tax 7%, means 1050 + .07 = $73.50 (sales tax charge)
Total computer with 25% off plus 7% tax equal:
$1050 + 73.50 = $1,123.50
Amir has saved $1200, so he has enough money to purchase the computer.
