Question

Could you please help me with this? It’s a problem from my grandson’s homework.

Answer 1

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

`\begin{gathered} 6\%*36.50 \\ =(6)/(100)*36.50 \\ =(6*36.50)/(100) \\ =(219)/(100) \\ =2.19\text{ dollars} \end{gathered}`

Now, we will add this $2.19 to the initial cost, we have

`2.19+36.50=38.69`

This gives $38.69.

Finally we will do a discount of 10%. 10% discount is

`\begin{gathered} 10\%*38.69 \\ (10)/(100)*38.69 \\ =(10*38.69)/(100) \\ =(386.9)/(100) \\ =3.869 \end{gathered}`

We will then subtract this 3.869 from 38.69, we get

`\begin{gathered} 38.69-3.869 \\ =34.821 \end{gathered}`

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
