Please help I rlly need it

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
