Answer:
Heidi (260 cookies)
Step-by-step explanation:
Megan's equation is given as y=8x, where x is the number of bags, and y the number of cookies:
#First calculate Heidi's total number of bags, cookies and cookies:

#Given that both Heidi and Megan make the same number of bags of cookies, Megan's cookies totals to:
