Samantha and her children went into a grocery store and she bought $7 worth of bananas and peaches. Each banana costs $0.40 and each peach costs $0.50. She bought a total of 15 bananas and peaches altogether. Determine the number of bananas and the number of peaches that Samantha bought.

b = bananas                 cost  40 b

p = peaches = 15-b      cost  50(15-b)      summed = 700             (700 cents)

 

40 b       +      50(15-b)     =     700        solve for 'b' the number of bananas     then  # peaches =  15-b
