June has $1.95 in dimes and nickels. she has a total of 28 coins. how many of each type of coin does she have.

June has 17 nickels and 11 dimes

Let the number of dime coins = d

Let the number of nickel coins = n

The total number of coins = 28

n  +  d   =  28(1)

0.1d + 0.05n = 1.95(2)

Make n the subject of the formula in equation (1)

n  =  28  -  d(3)

Substitute equation (3) into equation (2)

0.1d  +  0.05(28 - d)  =  1.95

0.1d  +  1.4  -  0.05d  =  1.95

0.05d  =  1.95 - 1.4

0.05d = 0.55

d  =  0.55/0.05

d  =  11

Substitute d = 11 into equation (3)

n  =  28  - 11

n  =  17

June has 17 nickels and 11 dimes

A dime = 0.10

A nickel = 0.05

N + D = 28 coins

Rewrite this as N = 28 -D

0.10D + 0.05N = 1.95

Replace N withe the rewritten equation above:

0.10D + 0.05(28-D) = 1.95

Use the Distributive Property:

0.10D + 1.4 - 0.05D = 1.94

Add the like terms:

0.05D + 1.4 = 1.95

Subtract 1.4 from both sides:

0.05D = 0.55

Divide both sides by 0.05

D = 0.55 / 0.05

D = 11

Nickels = 28 - 11 = 17

There are 11 dimes and 17 nickels.

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.

idk this answer sorry cant on this one.
