Solving 0.25n+0.05(n+5)=2.950.25n + 0.05(n + 5) = 2.95 by Clearing Decimals

To solve 0.25n+0.05(n+5)=2.950.25n + 0.05(n + 5) = 2.95, first distribute the 0.050.05 into the parentheses: 0.25n+0.05n+0.25=2.950.25n + 0.05n + 0.25 = 2.95 Combine like terms: 0.30n+0.25=2.950.30n + 0.25 = 2.95 To clear the decimals, multiply the entire equation by 100100, corresponding to the hundredths place: 100(0.30n+0.25)=100(2.95)100(0.30n + 0.25) = 100(2.95) Distribute the 100100: 30n+25=29530n + 25 = 295 Subtract 2525 from both sides to isolate the variable term: 30n=27030n = 270 Divide each side by 3030 to find nn: n=9n = 9 Checking the solution by substituting 99 back into the original equation evaluates to 2.95=2.952.95 = 2.95, confirming that the solution is n=9n = 9.
