Respuesta :

Solving a system of equations, we will see that Nora bought 2 apples and 6 bananas.

How many apples and bananas Nora did bought?

Let's define the variables:

  • x = number of apples.
  • y = number of bananas.

We know that She buys 3 times as many bananas as apples.

y = 3*x

The total cost is $5.

x*$1 + y*$0.50 = $5

Then we have a system of equations:

y = 3*x

x*$1 + y*$0.50 = $5

Replacing the first equation into the second one we get:

x*$1 + (3x)*$0.50 = $5

Now we can solve this for x.

x*$1 + x*$1.50 = $5

x*$2.50 = $5

x = $5/$2.50 = 2

So She bought 2 apples, and:

y = 3*x = 3*2 = 6

And 6 bananas.
