Jillian sold 15 ten-oz bags and 9 sixteen-oz bags.

Step-by-step explanation:

Let x represent number of 10-oz bags and y represent number of 16-oz bags.

We have been given that Jillian sold 24 boxes of cookies in total. We can represent this information in an equation as:

We are also told that 10 oz. box costs $3.50, while the 16 oz. box costs $5.00, so the cost of x 10-oz bags would be and cost of y 16-oz bags would be .

At the end of one week, she collected $97.50. We can represent this information in an equation as:

Now, we will use substitution method to solve our system of equations. From equation (1), we will get:

Substitute this value in equation (2):

Therefore, the number of 10-oz boxes sold be Jillian is 15.

Now, we will substitute in equation (1) to solve for y.

Therefore, the number of 16-oz boxes sold be Jillian is 9.

you never say the total so we cant find the percentage used for petrol
