Question

While shopping this week I misread my shopping list and bought 5 bread and 2 milk. I got a refund and bought 2 bread and 5 milk. This cost me $4.20 less than my first purchase. How do the prices of bread and milk compare?
A) Bread costs $1.40 more than milk.
B) Bread costs $0.60 more than milk.
C) Bread costs $0.42 more than milk.
D) Bread costs $0.60 less than milk.
E) Bread costs $1.40 less than milk

Answer 1

Suppose  x is the total cost for the first purchase, cost of the bread = b and cost of the milk = m
Then:-
 y     =    5b + 2m
y - 4.2 = 2b + 5m
Subtract:-
4.2 = 3b - 3m
b - m = 4.2 / 3 = 1.4

That is bread costs $1.40 more than the milk.   (Answer).  Its A
