Bella wants to purchase a t-shirt for $14.89. She knows that sales tax is an additional 5%, or , 1/20 of the price. To find the exact amount of the sales tax, she should multiply the purchase price by 0.05. A good estimate for the amount of sales tax is $0.74. A good estimate for the total price, including sales tax, is $15.63

Step-by-step explanation:

To know the X per cent of any number, we have to multiply that number by X, and then divide the result by 100. For example, 5 x X / 100. In the case, as we want to know the 5% of 14.89, the calculation would be 14.89 x 5 / 100. As 5 / 100 is equal to 0.05, we can know the percentage by multiplying the number by 0.05 as well.

Then, as 14.89 x 0.05 is equal to 0.74, that would be the sales tax, which added to the price of the t-shirt would give us a total price of $15.63 (14.89 + 0.74).
