Answer:
[tex]\frac{90}{3.5}[/tex]
Step-by-step explanation:
Let x be the number of helium balloons they can buy
- Write it out: 35 + 3.50x = 125
- Subtract 35 from each side, so it now looks like this: 3.50x = 90
- Divide each side by 3.50 to cancel out the 3.50 next to x. It should now look like this: x = [tex]\frac{90}{3.5}[/tex]
I hope this helps!
