Chapter 11.8, Problem 29CCR

To determine

To find:How much Seri pay for acrylic paints.

Answer to Problem 29CCR

Final amount Seri pay for the acrylic paint $=\$29.4$

Explanation of Solution

Given information:

Cost of acrylic paints $=C=\$35$

Discount percent $=p=20\%$

Sale tax rate $=r=5\%$

Cost of acrylic paints $=C=\$35$

Discount percent $=p=20\%$

We know

Discount Amount $=\frac{p}{100}\times C$

On substituting values

We get

  $\Rightarrow$ Discount Amount $=\frac{20}{100}\times 35$

  $\Rightarrow$ Discount Amount $=0.20\times 35$

  $\Rightarrow$ Discount Amount $=\$7$

Amount to be payed after discount $=$ Total amount $-$ Discount amount.

  $\Rightarrow$ Amount to be payed after discount $=$ $35-7$ .

  $\Rightarrow$ Amount to be payed after discount $=$ $=A=\$28$ .

Sale tax rate $=r=5\%$

Amount of tax $=\frac{r}{100}\times A$

  $\Rightarrow$ Amount of tax $=\frac{5}{100}\times 28$

  $\Rightarrow$ Amount of tax $=0.05\times 28$

  $\Rightarrow$ Amount of tax $=\$1.4$

Therefore,

Final Amount to be payed $=A+$ Amount of tax

  $\Rightarrow$ Final Amount to be payed $=28+1.4$

  $\Rightarrow$ Final Amount to be payed $=29.4$

Final amount Seri pay for the acrylic paint $=\$29.4$
