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

Answer:
3:1
Step-by-step explanation:
area is 2D while the perimeter is a length which is 1D. you can also about this in how the area is units squared while the perimeter is just units. so we need the square roote of 9 and 1, sqrt(9) = 3, sqrt(1) = 1. so the ratio of the perimeter is 3:1
