A store is having a 20%-off sale. It gives an additional 10% off if the item is still above $100 after the first discount. A jacket costs $149.99. Will you get the second discount and if so, how many dollars will you save in total?
yes;$42.00
yes;$14.49***
no
yes;$30.00
call it 150
.8 *150 = 120 so yes
.9 *120 = 108
so save about 42 total
calculate 150 times .2 (.2 is from 20 percent) this is 20 percent of 150. then take this number off 150 since it is 20 percent OFF. If it is more than 100, yes you will get the second discount. Now do the number yo got times .1 (.1 is from 10 percent.) this is 10 percent of that number. now add this number plus the 20 percent of 150 number. this is number of dollars saved in total. IF YOU HAVE ANY QUESTIONS, PLEASE ASK
100% - 20% = 80% or .8
100% - 10% = 90%
we
To calculate the total savings, we need to determine if the jacket price is still above $100 after the first discount.
To find the price after the first discount, subtract 20% from the original price:
$149.99 - (20% of $149.99)
To find 20% of $149.99, multiply $149.99 by 0.20:
$149.99 * 0.20 = $29.998
Next, subtract $29.998 from the original price:
$149.99 - $29.998 = $119.992
Now, we need to check if the price is still above $100. Since $119.992 is above $100, we qualify for the second discount.
To calculate the second discount, subtract 10% from the remaining price:
$119.992 - (10% of $119.992)
To find 10% of $119.992, multiply $119.992 by 0.10:
$119.992 * 0.10 = $11.9992
Subtract $11.9992 from the remaining price:
$119.992 - $11.9992 = $107.9928
The total savings will be the sum of the first and second discounts:
$29.998 + $11.9992 = $41.9972
Rounded to two decimal places, you will save $42.00 in total.
