Cindy bought a bouquet of roses for $18.75 and a bouquet of daisies for $9.50. How much will she pay in sales tax if the rate is
Rina8888 [55]

Answer: \$1.75

Step-by-step explanation:

We know the rate for sales tax is:

6.2\%=\frac{6.2}{100}=0.062

This means Cindy has to pay for the bouquet of roses and the bouquet of daisies plus the 6.2\% of the value of each item.

So, we have to calculate the sales tax for both items:

Sales_Tax=\$ 18.75(0.062) + \$ 9.50(0.062)=\$ 1.1625 + \$ 0.589

Hence:

Sales_Tax=\$ 1.7515 \approx \$1.75
