Question

Which equation can be used to find the total price, t, of the hay, considering a 6% tax rate added to the initial price?

A) t = 1.06 : 130

B) t = 106 : 130

C) t = 106(130)

D) t = 1.06(130)

Answer 1

The correct equation to calculate the total price of the hay including a 6% tax is D) t = 1.06(130), as it includes both the original price plus the additional tax.

Step-by-step explanation:

The correct equation to find the total price, t, of the hay, including a 6% tax, would be t = 1.06(130). This equation represents the initial price of the hay ($130) plus the 6% sales tax. To calculate the tax, you convert the percentage to a decimal and multiply it by the initial price. The 1.06 reflects the full price plus the 6 percent tax (1 represents the initial 100% of the given price, and 0.06 represents the 6% tax).

Option D) t = 1.06(130) is the correct answer. This can be calculated easily: 1.06 is the tax rate as a decimal which multiplies the original cost, $130, to find the total cost with tax.
