Answer:

The number of bikes she sell is 5 that is the option a .

Explanation:

Given:

Taylor sells bikes for $120 and pens $80.

She sold 12 items and made $1,160.

Now, to find the bikes she sell.

Let the number of bikes be
x.

And the number of pens be
y.

So, the total number of items:


x+y=12.


x=12-y........(1)

Now, the total money made by selling the bikes and pens:


120x+80y=1160.


120(12-y)+80y=1160.


1440-120y+80y=1160.


1440-40y=1160.

Adding both sides by 40y we get:


1440=1160+40y.

Subtracting both sides by 1160 we get:


280=40y.

Dividing both sides by 40 we get:


7=y.


y=7.

Now, putting the value of
y in equation (1) we get:


x=12-7


x=5.

Therefore, the number of bikes she sell is 5 that is the option a .
