A shopper buys 3 apples and two oranges and pays $1.78. Changing his mind he changes an orange for another ap?
the q is wrong, hence can't be solved
when you change an orange for an apple, you pay $.60 MORE
so even if oranges are FREE, an apple costs $0.60
and 3 apples cost $1.80
whereas the q says he paid $1.78 for 3 aopples AND 2 oranges !
edit:
===
it can be solved if he paid $0.06 i.e. 6 cents more
which is PROBABLY what the q was
let x cents be the cost of an apple. then
cost of an orange = (x-6) cents, and
3x + 2(x-6) = 178
5x - 12 =178
5x = 190
x = 38 cents
