Answer:
11 bottles
Step-by-step explanation:
make a proportion because if you're using the same rate proportions can show that it's equal
[tex]\frac{7}{90} = \frac{x}{140}[/tex]
cross multiply
[tex]7 *140[/tex][tex]= 980[/tex]
divide the answer by 90 to find x
[tex]980/90= 10.8[/tex]
round to 11 because you can't have 10.8 bottles
