Write an expression for 4 snacks at n pence each

The expression for the total price paid for all snacks (P pence) = 4n Pence will be; P=4n. Calculation: let the total price for the four snacks be P pence. let the four snacks be s1, s2, s3, and s4; their prices are: s1=n pence; s2 = n pence; s3=n pence; s4 = n pence. therefore; the total price paid for all snacks (P pence) = s1 price + s2 price + s3 price + s4 price = n+n+n+n = 4n hence; P=4n i. e. the total price paid for all snacks (P pence) = 4n Pence
