Answer: Third picture:
* 14 eggs
* 700 g of sugar
* 525 mL of oil
* 1400 g of banana
* 2380 g of fluor
* 105 mg of baking soda
Solution:
Using rule of three
4 eggs for 10 people
x eggs for 35 people
x=4*(35/10)→x=4*(3.5)→x=14 eggs
Similarly with the others ingredients:
Sugar=(200 g)*3.5→Sugar=700 g
Oil=(150 mL)*3.5→Oil 525 mL
Banana=(400 g)*3.5→Banana=1400 g
Flour=(680 g)*3.5→Flour=2380 g
Baking soda=(30 mg)*3.5→Baking soda=105 mg
