Question

3. Jada has a coin jar containing n nickels and d dimes worth a total of $3.65. The

equation 0.05n + 0.1d = 3.65 is one way to represent this situation.
Which equation is equivalent to the equation 0.05n + 0.1d = 3.657
A. 5n + d = 365
B. 0.5n + d = 365
C. 5n + 10d = 365
D. 0.05d + 0.1n = 365

Answer 1

C

Explanation:

Here, we want to find an equation in the options which is same as the equation given in the question;

The equation we are testing against is;

0.05n + 0.1d = 3.65

What we can do here is divide through by 0.01

So we will have;

0.05n/0.01 + 0.1d/0.01 = 3.65/0.01

= 5n + 10d = 365
