Answer:

Discount: $25.50

Sale prince: $59.49

Price after tax: $67.22

Step-by-step explanation:

To figure out the discount:

84.99 x .30 = 25.50  Rounded to the nearest penny

To figure out the sale price:

84.99 - 25.50 = 59.49  The original price minus the discount

To figure the cost after tax:

59.49 x .13 = 7.73  to find the tax, multiple the tax times the sale's price

7.73 + 59.49 = 67.22  Add the tax to the sale price.

Im doing decimals greatest to least and i need help with number 12 and 13
erma4kov [3.2K]

(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)

1. Just because a number looks big, doesn't mean it is big

Example: 1.00000000000001 < 1.1

just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"

2. Negative numbers are... opposite. and they are less than positive numbers

-3.4 > -4.1

Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers

I hope these tips helped!! :D
