Wanda earned $350 babysitting in July and August. She earned $90 more in August than in July. How much did she earn babysitting in July and August?

To calculate the total amount Wanda earned babysitting in July and August, we can follow these steps:

Step 1: Let's assume the amount Wanda earned babysitting in July is x dollars.

Step 2: We are given that Wanda earned $90 more in August than in July. So, the amount she earned in August is x + $90.

Step 3: The total amount Wanda earned in July and August is the sum of the amounts earned in each month. Therefore, the total amount is x + (x + $90).

Step 4: Since Wanda earned $350 in total, we can set up an equation: x + (x + $90) = $350

Step 5: Simplifying the equation, we can combine like terms: 2x + $90 = $350

Step 6: To isolate x, we can subtract $90 from both sides of the equation: 2x = $350 - $90

Step 7: Simplifying, we get: 2x = $260 Step 8: Finally, to find the value of x (the amount earned in July), we divide both sides of the equation by 2: x = $260 / 2

We can now solve for x to find the amount Wanda earned in July. Dividing $260 by 2, we find that Wanda earned $130 in July. To find the amount she earned in August, we can substitute this value back into the previous equation: x + $90 = $130 + $90 = $220. Therefore, Wanda earned $130 babysitting in July and $220 babysitting in August, making a total of $350 for July and August combined.
