Problema Solution
Alice bought12 apples and oranges for $2.51. If an apple costs 25 cents, and an orange costs 18 cents, how many of each did she buy
Answer provided by our tutors
Let
x = the number of apples bought
y = the number of oranges bought
$2.51 = 251 cents
Alive bought 12 fruits:
x + y = 12
The cost altogether is 251 cents:
25x + 18y = 251
We have the following system of equations:
x + y = 12
25x + 18y = 251
