Last week, Connor bought the A-wing Starfighter lego set. It retais for
199.99. He redeemed a 15% off coupon. He paid 7% sales tax. How much did he pay?

The total amount Connor paid = $181.9

Step-by-step 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:

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.

So, sales tax will be $11.9

The total amount Connor paid = $170+$11.9 = $181.9

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

$450 i think. hope this ☺
