Given the statement:
Banners at the school store were on sale for $2 off the regular price. Claude bought 6 banners on sale and paid a total of $18.
Write and solve an equation to find the regular price of one banner.
Solution:
Let x = price
The given statement can be represented as,
6x - 2 = 18
In order to determine the original price, we simply solve for x. To do so transpose -2 on the other side of the equation, hence in transposing a number, the sign changes.
6x - 2 = 18
6x = 18 + 2
6x = 20
Divide both sides by 6 in order to cancel out 6x leaving behind x.
6x/6 = 20/6
x = 20/6
x = $3.33…
Final answer:
x = $3.33…
