Answer:
After 59 months the new dryer will pay for itself.
Step-by-step explanation:
Let the new clothes dryer takes 'x' months to pay for itself.
Then the operating cost of the new dryer will be = 15x
Since cost of the new dryer = $590
So, total cost of the dryer in x months = $(590 + 15x)
Now we know old dryer's operating cost is = $25 per month
So, operating cost for x months = 25x
By the time when new dryer's total cost becomes equal to the old dryer's operational cost, the new dryer will pay for itself.
Now we can get the value of x by equating the old dryer's operational cost and the new dryer's total cost.
25x = 590 + 15x
25x - 15x = 590
10x = 590
x = 
x = '59 months'
Given situation: => 18 times 4 to the second power plus (9 minus 3) to the second powerLila answers 324 while Rob answers 360 in the given problem or equation.Now, let's try to solve it to know who got the correct answer:=> 18 x 4^2 + (9 - 3)^2, since we have a parenthesis in our equation, we need to solve it first=> 18 * 4^2 + (6)^2=> 18 * (4* 4) + (6 * 6)=> (18 * 16) + 36=> 288 + 36=> 324<span>Thus Lila got the correct answer</span>

Answer:
The probability that the month starts with the letter J or the letter M is 41.66%.
Step-by-step explanation:
Given that a month of the year is chosen at random, to determine what is the probability that the month starts with the letter J or the letter M, the following calculation must be performed:
January - March - May - June - July = 5 months
(5/12) x 100 = X
0.4166 x 100 = X
41.66 = X
Therefore, the probability that the month starts with the letter J or the letter M is 41.66%.
