Write an equation that can be used to solve the following: The sum of a number, n, and a number 5 larger than it is 41.
navik [9.2K]

n + n + 5 = 41 (4) 5n + n + 1 = 41

<em>n and "5 larger than n" </em>

'5 larger than n' = equivalent to n + 5

We now have n + n + 5

The problem says 41, thus;

<em>n + n + 5 = 41</em>

A man sells a sofa for rs 3210 making a profit of 7% what would have been his profit percent if he had sold it for rs 3360?
Digiron [165]
Let x be the original cost for the sofa.
X x (1 + 0.07) =3210
X = 3000
Now we know the cost for the sofa.
Let p be the profit percent.
3000 x (1 + p) = 3360
P = 0.12
So the percentage profit is 12%

Solve the following equation for x.<br> 0.1(x + 250) = 5,000<br> h
yan [13]

Answer:

x=49750

Step-by-step explanation:

0.1(x + 250) = 5,000

Divide each side by .1

0.1(x + 250)/.1 = 5,000/.1

x+250 =50000

Subtract 250 from each side

x+250-250 = 50000-250

x=49750
