Answer:
300
Step-by-step explanation:
Let the all cookies in the bakery be x.
Now we have that 45% percent of all cookies are 135 chocolate chip cookies, which can be represented as equation:
[tex]\frac{45}{100} *x=135[/tex]
If we multiply both sides by 100 we get:
[tex]\frac{45*x*100}{100} =135*100[/tex]
Simplifying we get:
45x=13500
Now we will divide each side by 4500
x=13500/45
The solution is x=300.
There are 300 cookies in the bakery.
