Eric gets paid $7 for each hour he works at the electronics store, plus an extra $2 for every store membership card he sells. How many memberships does he have to sell if he wants to make more than $40 for working 4 hours?

I need an inequality...

(7 * 4) + 2x > 40

Let's say the number of membership cards Eric sells is represented by the variable 'x'. To determine how many memberships he has to sell to make more than $40, we can set up an inequality.

First, let's determine his earnings from working 4 hours:

Earnings from working = $7 × 4 hours = $28.

In addition to this, he also earns $2 for each membership card sold. Therefore, his total earnings would be:

Total earnings = $28 + $2x.

To find the number of memberships he has to sell to make more than $40, we can set up the inequality:

Total earnings > $40,

which can be written as:

$28 + $2x > $40.

This is the inequality that represents the situation.

To determine how many memberships Eric needs to sell in order to make more than $40 for working 4 hours, we can create an inequality.

Let's break down Eric's earnings:
He earns $7 for each hour he works and an additional $2 for every store membership card he sells.

So for working 4 hours, he will earn:
$7 x 4 = $28

Now let's calculate how much he needs to earn in addition to his base pay of $28 to make more than $40. We'll represent the additional earnings from selling store membership cards as 'x,' the number of memberships he needs to sell.

Total earnings > $40
Base pay + Additional earnings > $40
$28 + $2x > $40

Therefore, the inequality representing Eric's earnings would be:
$28 + $2x > $40
