Alex wants to buy a case of drinks, he doesn’t have enough. The cost of the case is $30. He already has $2. He gets $8 every hour for work. How many hours does he need to work to get the amount he needs? Explain what your solution means in the context of the problem.

Alex will need to work 4 hours.

Step-by-step explanation:

We know that Alex already has $2. This means that to get $30 he now only needs to get $28. If he gets $8 per hour, we know that 8 x 3 = 24, but that isn't enough. In this case, 3 is how many hours he works. Because $24 isn't enough, he needs to work 4 hours to get $32 in order to buy the case. Even though he has more money than he needs, he will be able to buy the case and save some extra money.

3.5

Step-by-step explanation:

Wright, an equation first like this,

2+8x=30 because he needs 30 dollars but already has 2 and earns 8 dollars per hour.

Solve:

2 + 8x = 30

30-2= 28

28/8= 3.5 so he would need to work 3.5 hours.
