I don't know how to begin this one-help
Janie bought 2 pairs of identical jeans at a sale.she paid regular price for the 1st pair and paid half price forthe 2nd pair.if the the total cost was $45.00,what was the regular price of the jeans?
2x-1/2x=45 ??
That's right.
2x-1/2x=45
1.5x = 45
x = 45/1.5
x = ?
To solve this problem, we need to set up an equation based on the given information. Let's break it down step by step:
Let's denote the regular price of the jeans as 'x'.
According to the problem, Janie bought two pairs of identical jeans, where she paid regular price for the 1st pair and half price for the 2nd pair.
So, the cost of the 1st pair would be x, and the cost of the 2nd pair would be (1/2)x.
To find the total cost of the two pairs, we can add the cost of the two pairs together:
x + (1/2)x = 45.
Now, we can solve this equation for x. Let's simplify it:
Combining like terms, we have:
(3/2)x = 45.
To isolate x, the variable, we need to divide both sides of the equation by (3/2):
x = 45 / (3/2).
To divide by a fraction, we can multiply by its reciprocal:
x = 45 * (2/3).
Canceling out factors, we get:
x = 30.
Therefore, the regular price of the jeans was $30.
