Answer:

jhon can buy 7 cookies and the change is 2 pesos.

Step-by-step explanation:

if jhon can buy 10 cookies in 30 pesos just divide it to know how much the cookies each. 30÷10=3 (before the pandemic)In the problem when pandemic happens the price of cookies have increased.To know how much the cookies each during the pandemic, do the same operation.Just simply divide the 2 pesos to 8 pesos.8÷2=4 (during the pandemic)Since we know already how much cookies each just divide again the 4 to 30.30÷4=7 remainder 2 The 7 is the number of cookies that can be bought for 30 pesos and the 2 is the exchangeSo jhon can buy 7 cookies in 30 pesos and the exchange is 2 pesos.
