Help. Missing assignments r through the roof cause i don't know math.

Lin's father is paying for a $30 meal. He has a 15%-coupon for the meal. After the discount, a 7% tax is applied.

Step-by-step explanation:

1} He has to pay about $27.29

2} First off, his 15%-off coupon. 15% of 30 = 4.5

You need to subtract that from the original price, which is $25.50

However, since a 7% tax is applied, you have to find out what 7% of $25.50 is. Luckly, I've already got it for you ;)

7% of 25.50 is 1.785

The last step would be adding $1.785 to $25.50. This would equal $27.285

However, since you cannot go into the thousands place, you would have to round the answer to $27.29

{P.S. Hope you do well on the other problems :D}
