how do solar system and galaxies differ?

-- A galaxy is a collection of a huge number of stars ... possibly hundreds
of billions of stars in a galaxy. 

-- If a star has planets in orbit around it, then the star and its planets make up
one solar system.

-- There could be hundreds of billions of solar systems in one galaxy.

You can solve this problem using the formula m = 4a + 2c. m is for meatballs, a is for adults, and c is for children.m = 4 (25) + 2 (6)m = 100 + 12m = 112112 meatballs are required for a party of 25 adults and 6 children.
