Answer:

5n + 10 d = 365

Step-by-step explanation:

The equation that represents a coin jar containing n nickels and d dimes worth a total of $3.65 is as follows :

0.05n+0.1d=3.65

We need to find the equivalent expression.

We can write the above expression as follows :

[tex]\dfrac{5}{100}n+\dfrac{1}{10}d=\dfrac{365}{100}\\\\\text{LCM of 100 and 10 is 100}\\\\\dfrac{5n+10d}{100}=\dfrac{365}{100}\\\\5n+10d=365[/tex]

So, the equivalent expression is 5n + 10 d = 365
