SOLUTION
From the question given, the cost of the toy truck is $36.50 before tax.
Now, the store selling the toy truck adds a 6% sales tax. This means
Now, we will add this $2.19 to the initial cost, we have
This gives $38.69.
Finally we will do a discount of 10%. 10% discount is
We will then subtract this 3.869 from 38.69, we get
That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82
