3) Tara sold candles to raise money for new playground equipment at her school. Tara's candle sales total $50, and the school will keep 2/5 of that amount. The rest
of the money will go back to the candle company
Tara writes $50 x 2/5 to find out how much money is going to the candle company.
Tara's expression is incorrect. Explain the error in Tara's expression and explain
or show work to find the correct answer. In your explanation, include the correct
expression and the amount of money that will go to the candle company.

Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.

Step-by-step explanation:

50/5 = 10 which means that 1/5 of 50 = 10.

2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.

The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).
