I had this problem and i choose B which turn out to be incorrect. NOT B
The answer to the question is c
Given :
Ellis is making some beef burgers for his friends.
His recipe 500g of beef mince and 120g of cheese to make four burgers.
He buys 1.5 of mince and 400g of cheese, and makes as many burgers as possible.
To Find :
How much cheese will he have left over.
Solution :
500 g and 120 g of beef mince and cheese respectively make 4 burgers.
125 g and 30 g of beef mince and cheese respectively make 1 burgers.
Now, we will keep increasing the ingredients until there is any shortage of any ingredients.
1000 g and 240 g will make 8 burgers.
1500 g and 360 g will make 12 burgers.
1625 g and 390 g will make 13 burgers.
Cheese left is ( 400 - 390 ) g = 10 g.
Therefore, 10 grams of cheese will be left.
Ok,so the equation is 2x +8=100 but their are 4 sides, so you will add 2x+2x and 8+8, so that will equal 4x +16=100. subtract 16 from 100 and it will give you 84.divide 84 by 4 and it will give you 21. to check your answer multiply 24 times add 16 and it gives you 100
