Someone help I have no clue how to do this

Using proportions, it is found that their mom put 90 candies in the bowl.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

For this problem, the total amount is of x, hence, from the text:

Tom's fraction is $\frac{1}{2}x$ .

Carlos' fraction is $\frac{1}{3} \times \frac{1}{2}x = \frac{1}{6}x$ .

Mary's fraction was of: $\frac{3}{5} \times \left(x - \frac{x}{2} - \frac{x}{6}\right) = \frac{1}{5}x$

The remaining fraction after Mary was:

$x - \frac{x}{2} - \frac{x}{6} - \frac{x}{5} = \frac{30x - 15x - 5x - 6x}{30} = \frac{2x}{15}$

This amount is of 12, hence the total number of candies was:

2x/15 = 12

2x = 15 x 12

x = 15 x 6

x = 90.

A big-screen TV that previously sold for $2,400 has been marked down to $2,040. What is the percent of decrease?

Hitman42 [59]

[~Answer~] (8.):
Heyyy. I'm Avery, and I'm always here to help!

I believe the percent may be 15% ($2,400 - 15% = $2,040)

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

[~Answer Explanation~}:

The percent of the difference is the rate of the difference * 100%

the percent of the difference = .15 * 100% = 15%

since the new price is less than the old price, that is the percent of the decrease.

(See if it'll work): $2,400- 15% = $2,040

And there's your answer <33
