Assuming they work until their cost become the same, obviously.
The difference between the first charge of painter A and painter B = 376 - 280 = 96.
The hourly cost difference between painter B and painter A = 15 - 12 = 3.
So, painter A in the first hour has 96 more dollars than painter B, and as every hour pass, the difference goes down by 3 (as painter B gets 3 more dollars every hour)
Therefore, it would take 96 : 3 = 32 hours for the cost to be the same
Recheck : After 32 hours, painter A has 376 + 32 x 12 = 760 (dollars)
painter B has : 280 + 15 x 32 = 760 (dollars)
Digit two from left to right would be 200,000 from right to left it would be 70
Ten, but you have to do it to both sides.
To me to start solving thus you have to minus all the numbers by 25 which was the given number in the equation.
hope this helps.
The given expression is
And we have to solve for N.
TO solve for N, first we do cross multiplication, that is
And to solve for N, we have to divide both sides by D, that is
And that's the required value of N .
