Hi can anyone help to solve this question?
Hanna paid $85.10 for a total of 10 brownies and pies. She had 2 more brownies than pies. Each pie cost $8.90 more than each brownie. How much did she pay for one pie?
Can we draw a model to solve the problem?
Thanks.

No. of pies=(102)/2=4
Each pie costs $8.90 more than each brownie.
Therefore, 4 pies cost 4x$8.90 =$35.60 more
Cost of each brownie= ($85.10$35.60)/10=$4.95
Cost of each pie=$4.95+$8.90=$13.85

Method is no diff. from rathanackumr, but I would like to present the model is a slightly different view, which should be much easier for the student to understand the solution.
