well first we figure out how much our 15% discount was when our total was 96.60 soo we do that by multiplying 96.60 and 0.15 to lets do that
96.60 x 0.15 = 14.49
so now we subtract that value
96.60 - 14.49 = 82.11
so our first value is $82.11
now lets find out second one* it has a little bit more work...
first of all we need to add 0.79 to our 96.60 amount until we get to $100 so lets do that :)
96.60
+ 0.79
*****
97.39
+ 0.79
**
98.18
+ 0.79
**
98.97
+ 0.79
**
99.76
+ 0.79
*****
100.55
so finally we got to our 100 value by adding 0.79 five times!
now we can find our 20% value
so lets multiply 100.55 times 20% or 0.20:)
100.55 x 0.20 = 20.11
so lets subtract and find our discounted price
100.55 - 20.11 = 80.44
Now we have both of our discounted prices! lets subtract them to find the difference
$82.11 - $80.44 = $1.67
she will pay $1.67 less with the 20% discount and added gum:)
i hope this was helpful:)
and don't forget 2
MARK ME BRAINLIEST! :D
