Question

A sweater costs $$\mathrm{\$}29.99$$ plus a $$6\mathrm{\%}$$ sale tax. How much will the sweater cost with the tax , rounded to the nearest penny?

Answer 1

Hint: As we have the sweater cost given $$\mathrm{\$}29.99$$ and also with the $$6\mathrm{\%}$$ of the sales tax. Here we have to find sweater cost with the tax which rounded to the nearest penny. Here we have to multiply the $$6\mathrm{\%}$$ of sales tax with the sweater cost and at last we have to add it with the sweater cost. In this way we have found the total amount of sweaters.

Complete step by step solution:
As we have the cost of sweater will be $$\mathrm{\$}29.99$$ and the sale tax will be $$6\mathrm{\%}$$
So, the $$6\mathrm{\%}$$ tax corresponds to an amount of money :
$$\therefore 6\mathrm{\%}=0.06$$
Now,
We have to multiply the above value with the cost of the sweater which is given.
So,$$0.06\times 29.99=\mathrm{\$}1.7994$$.
As we take the round off value of $$\mathrm{\$}1.7994$$ will be $$\mathrm{\$}1.80$$.
Then, the total will be $$29.99+1.80=\mathrm{\$}31.79$$

$$\mathrm{\$}31.79$$ will be the sweater cost with the tax rounded to the nearest penny.
