Aman has two more nickels than dimes. he has $1.15 in all. how many coins of each kind does he have?
which equation can be used to solve the problem?

5x + 10(x + 2) = 115
5(x + 2) + 10x = 115
x + x + 2 = 115

5(x +2) + 10x = 115

Number of nickels = 9 and dimes = 7

Step-by-step explanation:

Let the number of nickels a man has = y

and dimes = x

Then by the statement of the question we can form the equation as

y = x + 2(1)

(.05)y + (.10)x = 1.15(2)

By multiplying equation 2 by 100

5y + 10x = 115(3)

Now we put the value of y from equation 1 in the equation 3

5(x + 2) + 10x = 115

5x + 10 + 10x = 115

15x + 10 = 115

15x = 105

x = 7

y = 7 + 2 = 9

Number of nickels = 9 and dimes = 7

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
