the complete question in the attached figure

we have that
x----------------> represents the number of spoonfuls of brand A 
y----------------> represents the number of spoonfuls of brand B 
Brand A---------------- > Calcium. Iron Vitamins ------ >  5 4 7  milligrams
Brand B---------------- > Calcium. Iron Vitamins ------ >  4 6 4  milligrams

Steve needs to take at least
Calcium milligrams >=24
Iron milligrams >=15
Vitamins milligrams >=16

I proceed to calculate the system inequalities

for Calcium
5x+4y>=24

for iron
4x+6y>=15

for Vitamins
7x+4y>=16

using a graph tool to solve the system of inequalities
see the attached figure

the answer is the point (1,5) and the point (4,1) are solution
