Answer:
a)78
b)82.95
Step-by-step explanation:
To get the amount something is marked up you just need to multiply it by
1+0.(the%)
so in this case you multiply 60 by 1.30 to get 78
To get a discount you just have to do the same but without the +1
so 88*0.15
should get you the discount amount (13.2)
which you subtract from the original number (88-13.2 = 74.8)
now to get sales tax you would multiply the 79 by 0.05 which is 3.95
and add that to the total of 78.75 since sales tax applies AFTER coupons

Step-by-step explanation:
3x^3+2x^2-32x+2 | x-3
-----------------
-3X^3+9x^2 3x^2 +11x+1
-------------------------
/ 11x^2-32x+2
-11x^2+33x
------------------
/ x+2
-x+3
-------
/ 5
⇒ (3 x^3+2X^2-32x+2) : (x-3)= 3x^2+11x+1 rest 5
