Answer:
n = 13
Step-by-step explanation:
0.05n + 0.10(n + 3) = 2.25
First expand the terms in the bracket
We have
0.05n + 0.10n + 0.3 = 2.25
Add the like terms
That's
0.15n + 0.3 = 2.25
Subtract 0.3 from both sides
We have
0.15n + 0.3 - 0.3 = 2.25 - 0.3
0.15n = 1.95
Divide both sides by 0.15
That's
[tex] \frac{0.15n}{0.15} = \frac{1.95}{0.15} [/tex]
We have the final answer as
n = 13
Hope this helps you
Answer:
Step-by-step explanation:
0.05n+0.10(n+3)=2.25
0.05n +0.10n +0.3=2.25
0.15n +0.3=2.25
0.15n=2.25-0.3
0.15n= 1.95
0.15 0.15
n=13
