Answer 1

In the expression 15.85(1+x), 1+x represents the percent of original price being paid, which is increased by the sales tax.

Therefore, the correct answer is: option 'percent of original price being paid'.

Step-by-step explanation:

In the given equation, the x represents the sales tax written in decimal form, and 1+x indicates that the original price is being increased by a certain percentage.

Therefore, 15.85(1+x), the term 1+x represents the percent of original price being paid.

For example, if x is 0.08 (which represents an 8% sales tax), then 1+x is 1+0.08=1.08. This means that the total cost of the toy will be 108% of the original price, including the sales tax.

To calculate the total cost of the toy, you would multiply the original price (15.85) by 1+x (1.08):

15.85 x 1.08 = 17.118.

Therefore, the total cost of the toy, including the sales tax, would be $17.12 (rounded to the nearest cent).
