has a total of \$7.48. He has ten fewer dimes

as dimes. How many of each coin does he

have?

Brandon has 28 pennies, 18 dimes, and 108 nickels.

Let's start by writing equations:

pennies = 10 + dimes,

nickels = 6 x dimes.

You know Brandon used a number of pennies ending in either 3 or 8, since he has a total of \$7.48.

I didn't know how to proceed from here, so I had to guess and check lol.

d = p - 10                               dime value =   10 ( p-10)

n = 6d = 6 ( p-10) = 6p -60     nickel value = 5 ( 6p-60)

p

p +    10( p-10)     +   5( 6p-60)       =   748

p = 28     then d = 18      n = 108

Mathematics is the science and study of quality, structure, space, and change. ... Through abstraction and logical reasoning mathematics evolved from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects
