Question

A patient is advised by his doctor to reduce his daily soda intake by 25%. Currently, he drinks 4.5oz. cans of soda per day. How many ounces of soda can the patient drink if he reduces his intake by 25%?

Answer 1

Answer: 3.375oz

Explanation

Given

• Reduce his daily soda intake by ​25%.

,

• Currently, he drinks 4.5oz. cans of soda per day.

,

• Ounces of soda can the patient drink if he reduces his intake by 25​%?

We have to build a relation, where 4.5 is our 100% and x is 75% (100 - 25 = 75%):

$\frac{x}{75}=\frac{4.5}{100}$$x=\frac{4.5}{100}\cdot75$

Solving for x:

$x=4.5\cdot0.75$$x=3.375$
