Please help and explain how you solved: Alla has $18.05 in her pocket. Write a function showing the dependence of money left (L) in her pocket after buying n markers of $0.95. Find the domain and range of the function.

f(L) = -0.95L + 18.05

domain:  0 ≤ x ≤ 19

range:  0 ≤ y ≤ 18.05

Step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
