equation E: 15b=21

Jada has a coin jar containing n nickles and d dimes worth a total of $3.65

The equation 0.05n + 0.1d+3.6s is one way to represent this situation.

Which equation is equivalent to the equation 0.05n + 0.1d =3.65

A. 5n+d=365

B. 0.5n+d=365

C. 5n+10d=365

D. 0.05d+0.1n= 365

Answer 1

If you multiply both sides by 100, you derive

5n + 10d = 365 (answer choice c).

It is usually easier to work with whole numbers than decimal fractions.
