Click For Summary
To solve the problem of determining how many high-quality songs were downloaded, a system of equations is suggested. The first equation is based on the total size of the downloads: 2.3S + 4.2H = 4077, where S represents standard versions and H represents high-quality versions. A second equation is needed, which can be derived from the total number of downloads: S + H = 1120. By solving these two equations simultaneously, the number of high-quality songs downloaded can be calculated. This approach provides a structured method to tackle the word problem effectively.

My homework question is "the standard version of a song is 2.3mb and high quality is 4.2mb. There was 1120 downloads for a total of 4077mb. How many high quality songs were downloaded?" I'm having an issue creating the formula needed to solve this word problem!

Hi reader1018,

I think we can set up a system of equations to solve this. Let's call $S$ the number of standard versions downloaded and $H$ the number of high quality versions downloaded. We are told that $2.3S+4.2H=4077$. We need a second equation though to solve for both variables. What else do we know?
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
