Savings Briana and her sister Molly both want to buy the same model bicycle. Briana needs $73 more before she can afford the bike. Molly needs $65 more. If they combine their money, they will have just enough to buy one bicycle that they could share. What is the cost of the bicycle?how to set up and solve this?

Sagot :

Let the cost of the bicycle be $x

Since Briana needs $73 more, the present amount of money she has will be $(x-73)

Since Molly needs $65 more, the present amount of money she has will be $(x-65)

Now, combining what they have now, they will be able to buy just one bicycle

This means that;

x - 73 + x -65 = x

2x - 138 = x

2x - x = 138

x = $138

The cost of the bicycle is $138
