The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express
ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

x+x\times \frac{13.6}{100}=57

x+0.136x=57

1.136x=57

Divide both the sides by 1.136.

\frac{1.136x}{1.136}=\frac{57}{1.136}

x=50.176

x\approx 50

Therefore the number of cases prior to the increase is 50.
