what are the 2 equations?
A shopper buys 3 apples and 2 oranges and pays $1.78. Changing his mind, he exchanges an orange for another ap?
what we do is call apples A and oranges O,
then we can make:
3A + 2O = 1.78
It doesn't say in the question, but I'm guessing the price stays the same? Which means (after the exchange)
4A + O = 1.78

3+2 =5 , 5 items totaling a price of 1.78 , divide 1.78 by 5 and work out the value of 2 and half of that is what he exchanges for anouther apple. use the caluculator in accessories.
3A + 2O = 1.78
4A + O = ?
