Answer:
percentage change is 10% increase.
Step-by-step explanation:
Ramiro worked last week = 20 hours
He worked this week = 22 hours
Difference in time = 22 - 20 = 2 hours
Here we can see the number of hours are increasing.
Percent change formula = [tex]\frac{(V_2-V_1)}{V_1}\times 100[/tex]
V₁ = Old Value
V₂ = New value
Now put the values in the formula
= [tex]\frac{(22-20)}{20}\times 100[/tex]
= [tex]\frac{2}{20}\times 100[/tex]
[tex]=\frac{200}{20}[/tex]
= 10%
percent change is 10% increase from last week to this week.
