Answer:
Calcium in a cup of milk x = 330 mg
Calcium in cup of spinach y = 150 mg
Step-by-step explanation:
Let call " x " and " y " quantity of calcium ( in mg ) in a cup of milk, and spinach respectively, then according to problem statement we have:
3*x + 1*y = 1140 and 2*x + 2*y = 960
We have a two equation system, we need to solve for x and y then:
y = 1140 - 3*x
2*x + 2 * ( 1140 - 3*x ) = 960
2*x + 2280 - 6*x = 960
-4*x = - 2280 + 960
-4*x = - 1320
x = 1320 / 4 ⇒ x = 330 mg
And y = 1140 - 3*x
y = 1140 - 3* 330 ⇒ y = 1140 - 990 ⇒ y = 150 mg
