Larry and Donna bought a sofa at the sale price of $1,344. The original price of the sofa was $1,920. Find the discount rate
velikii [3]

Answer:

30% discount

Step-by-step explanation:

To find the percent discount write a proportion.

\frac{1344}{1920}=\frac{x}{100}

Cross multiply numerator with denominator of each fraction to solve for x.

1344(100) = 1920(x)

134400 = 1920x

70 = x

This means you pay 70% of the price. The discount was 30%.

Increase 14187.13 by 4.5%
Ksivusya [100]
If you increase a number by 4.5%, then you're adding 4.5% of that number to 100% of that number. So essentially you just multiply 14187.13 by 104.5%, or 1.045 to find the answer, which is 14,825.55.
