Need help ASAP will give if correct

0.80c + 12 ≤ 28.40

c ≤ 20.5

Step-by-step explanation:

c represents # of cups of coffee

0.80 is the price per cup of coffee

so in the inequality it's 0.80c

$12 is how much the mug costs so it's + 12

for solving the inequality isolate c :

0.80c + 12 ≤ 28.40

0.80c ≤ 16.4

c ≤ 20.5

so this means that charlie can buy 20.5 cups of coffee and a $12 mug and the total won't exceed the $$$ on his coffee stop card
