Four friends go to the waterpark.They each purchase a locker for $2 a person. They decided to each purchase a lunch voucher as well. If altogether they spent a total of $28, how much did each lunch voucher cost? Write an equation to solve. 

Let the cost of each lunch voucher be represented by $ x $.

The four friends each paid $2 for a locker, so the total cost for lockers is $ 4 \times 2 = 8 $ dollars.

The total amount spent was $28, which includes both the locker costs and the lunch vouchers.

Since they all purchased a lunch voucher, the total cost for the lunch vouchers is $ 4x $.

The equation to represent this situation is:

\[
8 + 4x = 28
\]

To solve for $ x $:

1. Subtract 8 from both sides:

\[
4x = 28 - 8
\]
\[
4x = 20
\]

2. Divide both sides by 4:

\[
x = \frac{20}{4}
\]
\[
x = 5
\]

Thus, each lunch voucher costs $5.

2. If each friend had a discount on the locker and paid $1.50, what would the new total cost be?
3. What if the friends shared one locker for $2, how would that affect the equation?
4. How would the equation change if they each bought a drink for $3 in addition to the lunch voucher?
5. What would the total be if the price of the lunch voucher was increased by 10%?
