Answer:
5800
Step-by-step explanation:
Let's say that the amount of cases last week is x.
When it says 23% more than x, it means 123% of x.
With this, we can make an equation.
[tex]\frac{123x}{100}=7134\\[/tex].
To solve:
1. Multiply both sides by 100
123x = 7134*100
123x = 713400
2. Divide both sides by 123
x= 713200/123
x= 5800
