Suppose you plan to save $12 per week.You have already saved $7.50.In how many weeks will you have saved at least $100?
100 - 7.50 = 92.50
92.50 / 12 = ?
34532
8 weeks.
100-7.5 = 92.50
92.50/12 = 7.70833333
This means 8 weeks.

To determine the number of weeks required to save at least $100, we can set up an equation. Let's assign a variable to represent the number of weeks.
Let's call the number of weeks "x."
We know that you plan to save $12 per week, so the total amount you will save after x weeks is 12x.
We also know that you have already saved $7.50.
So, the equation becomes:
12x + 7.50 = 100
Now, we can solve this equation for x to find the number of weeks.
Step 1: Subtract 7.50 from both sides of the equation:
12x = 100 - 7.50
12x = 92.50
Step 2: Divide both sides of the equation by 12 to isolate x:
x = 92.50 / 12
x = 7.7083 (rounded)
Therefore, you will need approximately 7.7083 weeks to save at least $100. Since weeks cannot be fractional, we can round this value to the nearest whole number.
Hence, you will need 8 weeks to save at least $100.
