Question

The class collected a total of 1943 pennies in 4 weeks. Sam brings in 125 pennies each week. Approximately what percent of the total pennies collected did Sam bring?

Answer 1

Sam brought in about 25.74% of the total pennies collected by his class, by contributing 125 pennies each week for 4 weeks against the total collection of 1943 pennies.

Step-by-step explanation:

To find the percentage of the total pennies collected that Sam brought in, we first need to calculate the total number of pennies Sam contributed over the 4 weeks. Since Sam brings in 125 pennies each week, we multiply this number by 4:

125 pennies/week × 4 weeks = 500 pennies

Next, to find the percentage that Sam contributed, we set up a proportion where Sam's contribution is to the total collection as x is to 100%:

x / 100% = Sam's contribution / Total collection

This can be solved by cross-multiplication:

x × Total collection = Sam's contribution × 100%

Let's plug in the numbers:

x × 1943 = 500 × 100%

Now we solve for x, which represents the percentage:

x = (500 × 100%) / 1943

x ≈ 25.74%

Therefore, Sam brought in approximately 25.74% of the total pennies collected by the class.
