Answer:
the answer is a.
Step-by-step explanation:
I plugged your data into a graphing calculator, and got a quad reg in the picture.
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
The bakery starts a week with 100% quarts of milk.
In the course of the week they use 70%, meaning the remainder is 30% quarts of milk.
Therefore, the remaining quarts are equivalent to 30%
thus, 36 = 30% to get 100% ;
(36/30) ×100 = 120
Therefore, the bakery started the week with 120 quarts of milk
