You bought 4 bananas and 5 apples at the store for .50 the next day you bought 10 bananas and 3 apples at the store for .40. The bananas and apples had the same price both days. How much does each cost?


Bananas cost: $0.25  Apples cost: $0.30 4b+5a=2.50 10b+3a=3.40  You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have 12b+15a=7.50 50b+15a=17 Subtract them and end up with -38b=-9.5  solve: b=0.25, substitute b in any equation and get a=0.30 Hope this helped
