Finger [1]3 years ago
3 0

Answer:

7.04% decrease

Step-by-step explanation:

Lets use 5 example

5*0.17=0.85

5-0.85=4.15

4.15*0.12=0.498

4.15+0.498=4.648

PLEASE ANSWER I WILL MARK AS BRAINLIEST
Tomtit [17]

Answer:

Six

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}

(c) Banana flavouring

V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL }

2. Calculate the total volume

Chlorpheniramine = 100  mL

Lidocaine               =   59

Banana flavouring =  <u>   2.5    </u>

TOTAL                    =  162 mL

3. Calculate the number of doses

\text{Doses} = \text{162 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{16.2 doses}\\\\\text{You can't take a fraction of a dose, so the there are $\large \boxed{\textbf{16 doses}}$}
