Answer:
$4.40
Step-by-step explanation:
To find the cost of each coffee in dollars, you can use the inequality:
2.39 + 4c < 20
This inequality states that the total cost of the cookie and the four coffees is less than $20.
To solve for c, the cost of each coffee in dollars, you can start by combining like terms on the left-hand side of the inequality:
2.39 + 4c = 20 - 2.39
4c = 17.61
Then, divide both sides of the inequality by 4 to solve for c:
c = 17.61 / 4
c = $4.40
So, the cost of each coffee in dollars is $4.40.
