(2/5)k + (1/10)k = (1/2)k - 1
0.4k + 0.1k = 0.5k - 1
We need to solve for k.

Subtract 0.4k from both sides
0.4k - 0.4k + 0.1k = 0.5k - 0.4k - 1
0.1k = 0.1k - 1

Subtract 0.1k from both sides:
0.1k - 0.1k = 0.1k - 0.1k - 1
0 = -1

Impossible. The equation has no solution.

JulijaS [17]

Answer:

They paid $4.00 per ticket

Step-by-step explanation:

<u>Step 1:  Convert words into an inequality</u>

A family buys 6 tickets to a show. They also pay $3 parking fee. They spend $27 to see the show.

6t + 3 = 27

<u>Step 2:  Solve for t/tickets</u>

6t + 3 = 27

6t + 3 - 3 = 27 - 3

6t / 6 = 24 / 6

t = 4

Answer:  They paid $4.00 per ticket
