Answer:
$1165.73
Step-by-step explanation:
We have 395.95+159.95+750+129.95=1435.85. Once we have this, we add the student discount of -25%. This rounds to 358.96. We subtract this from the total and get 1076.89. After the student discount, we add the sales tax of 8.25%. This adds a total of 88.84 to the final amount. After adding this we get a final total of $1165.73
1/1 = 1
1/2 = 0.5
1/3 = 0.3
1/4 = 0.25
1/5 = 0.2
vvvvvvvv
1/6 = 0.16
^^^^^^^^^
If there was 20% taken off you add 20% back on and that is how you will get your answer. So take 760 plus the 20% which gives you 912 dollars
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
The first equation uses the first and second coupons. the coupon (1-y)40 will take y% off of the dress pants so the answer is 40(1-y)
