Answer:
a) Given expression,
12% of 312
Since 100% of 312 = 312
⇒ 10% of 312 = 31.2,
⇒ 1% = 3.12
⇒ 2% = 2 × 3.12 = 6.24
So, 12% of 312 = 10% of 312 + 2% of 312
= 31.2 + 6.24
= 37.44
b) Given,
Total number of servings = 312,
The percentage of vitamin C in each serving = 12%,
Thus, the total amount of the vitamin C in 312 servings = 12% of 312
= 37.44,
Hence, the question can be asked about the total amount of the vitamin C.

Answer:
x = 4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20x+5−0=5x+(32.5)(2)
20x+5+0=5x+65
(20x)+(5+0)=5x+65(Combine Like Terms)
20x+5=5x+65
20x+5=5x+65
Step 2: Subtract 5x from both sides.
20x+5−5x=5x+65−5x
15x+5=65
Step 3: Subtract 5 from both sides.
15x+5−5=65−5
15x=60
Step 4: Divide both sides by 15.
15x
15
=
60
15
x=4
