Set up and solve equations for the following business situations.
The Cookie Monster sells oatmeal cookies for $1.30 per pound and peanut butter cookies for $1.60 per pound.
a. If total cookie sales last week amounted to 530 pounds, valued at $755, how many pounds of each type of cookie were sold?
b. What dollar amount of each type was sold?
(a)
To calculate: The pounds of oatmeal cookies and from peanut cookies sold, if the Cookie Monster sold

Step4: Solve the equation by rearrange the unknown values to the left side and known values to the right side of the equal sign.
Step5: Prove the solution by substituting the value obtained from step 4 in the equation formed in step 4 then check the left and right of the equation if, they are equal then the answer is correct.
Calculation:
Underline the keyword by using the table of of key word.
The sum of price of each item multiply by its quantity equals total price,
Suppose that X be pounds of peanut cookies sold.
Consider the cost of
Therefore, the pounds of oatmeal cookies sold is
Consider the charge per pound of oatmeal cookies is
Consider the total amount earned from the sale of
Now solve the equation
(b)
To calculate: The amount earned from the sale of oatmeal cookies and from peanut cookies, if the Cookie Monster sold
