Question

The total cost of an electronic photo

display comes to $100. The price
y plus the tax of $6 equals $100.
Write an equation to find the price
of the electronic photo display.

Answer 1

P = y * 1.06

Explanation:

Let y be the net price (no tax), t the tax (as a factor) and P the total price (tax included),

P = y * t

From the info provided, we know that for each 100 USD, 6 USD is tax, so 6%,

TIP: By multiplying by 1.06 we add the 6% to the net price (6% is 0.06)

P = y * 1.06
