You have $30 to buy muffins. However, at the shop you can only buy 1 muffin for $4. a) Write an inequality from the above information
b) Solve this inequality to find the number of muffins you can buy
c) How much money will you have left over​

a)4x ≤30 where x is the quantity of muffins b) The greatest amount of muffins you can purchase is 7. c) 2dollars

Step-by-step explanation:

a) 4x ≤30 where x is the quantity of muffins

b) 4x≤30

x≤7.5

It means that you can buy only 7.5 muffins or less. But you can buy only whole muffin, so you can buy 7 muffins or less. The greatest amount of muffins you can purchase is 7.

c) If you purchase 7 muffins you spend 7*4= 28 dollars

And then you will have 30-28=2dollars
