Answer:
The total amount Connor paid = $181.9
Explanation:
Cost of A-wing Starfighter lego set = 199.99
Coupon = 15%
Sales tax = 7%
We need to find total amount he paid.
First he redeemed the coupon, so we will find 15% of 199.99 and subtract this amount from actual cost
15% of 199.99
Solving:
![15\% \ of \ 199.99\\=(15)/(100)*199.99\\=29.99](https://img.qammunity.org/2021/formulas/mathematics/college/2k88lehl4xp6v80n0ox445xv1sra7n32m2.png)
So, He received discount of $29.99
The cost will be: $199.99 - $29.99 = $170
Now, there is 7% sales tax. We will find 7% of 170 and add that amount to the cost.
![7\% \ of \ 170\\=(7)/(100)*170\\11.9](https://img.qammunity.org/2021/formulas/mathematics/college/gofc2yk5tmj4f4ql2xzw29i5sjme17gegt.png)
So, sales tax will be $11.9
The total amount Connor paid = $170+$11.9 = $181.9
