Keddy spent $50 more money this week than last week.This is a 25% increase from the money he spent last week.How much money did he spend last week?

To solve this problem, we need to set up an equation based on the information given.

Let's denote the amount of money Keddy spent last week as X.

According to the problem, Keddy spent $50 more this week than last week, which is a 25% increase from the money he spent last week.

So, we can set up the equation as follows:

X + 50 = X + 0.25X

Solving this equation will give us the amount of money Keddy spent last week.

First, simplify the right side of the equation:

X + 50 = 1.25X

Then, subtract X from both sides to isolate the variable term:

50 = 0.25X

Finally, divide both sides by 0.25 to solve for X:

X = 50 / 0.25

X = $200

So, Keddy spent $200 last week.
