Question

3. Mojirayo has a coin jar containing nickels and dimes worth a total of$3.65. The equation 0.05n + 0.1d = 3.65 is one way to represent thissituation. Which equation is equivalent to the equation 0.05n + 0.1d + 3.65?A. 5n + d = 365B. 0.5n + d = 365C. 5n + 100 = 365D. 0.05d + 0.1n = 365

Answer 1

The given equation,

0.05n+0.1d=3.65

Now solving,

$\frac{5}{100}n+\frac{1}{10}d=\frac{365}{100}$

Furthur simplifying,

$5n+10d=365$

The answer is C.5n+10d=365
