Answer:
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}
