The price of a shirt is $25.50, but you have a coupon that lowers the price by 30%. What is the price of the shirt after using the coupon?

Concept: Price Change

25.50 × 0.30= 7.6525.50-7.65=17.85

5.36201 rounded to the first decimal place will be 5.4

this is because there is a general rule that numbers from 5 to 9 are rounded up to the next highest number. thus we need to look at the first 2 decimal places, 5.36

6 is higher than five, so it will be rounded up to 10. you cannot have a double digit number in a single decimal place, so you carry it over to the next one to the left, in this case being 3. 3 + 1 = 4, and hence we attain 5.4
