Answer:
400%
Step-by-step explanation:
We can write a percent proportion:
600/x = 150/100
a:b = c:d
a and d are linked and b and c are linked. So if a is missing, you would do (b*c)/d to get a, if b was missing, you would do (a*d)/c to get b, etc.
So over here we do
(600*100)/150 = 60,000/150 = 400, so x = 400, so that means it's 400% of 150
We can also use benchmark fractions which I find much easier:
100% of 150 is 150.
So 200% of 150 is 300
So 300% of 150 is 450
And 400% of 140 is 600
Every time it increases by 100%, it also increases by 150 on the other side, which makes sense
Let me know if you have any questions.
For the fast food company:
Cost of 100 hamburger buns = $120
Hence, cost of 5 hamburger buns = (5*120)/100 = $6
For the customer:
Cost of 3 hamburger buns = $6
Hence, cost of 100 hamburger buns = (100*6)/3 = $200
The fast food company bought 100 buns for $120, and sold those 100 buns for $200.
Hence, the profit per 100 buns = 200 - 120 = $80
