Question

Last week, Ramiro worked 20 hours. This week he worked 22 hours. What is the percent change from last week to this week?

Answer 1

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 = $\frac{(V_2-V_1)}{V_1}\times 100$

V₁ = Old Value

V₂ = New value

Now put the values in the formula

=  $\frac{(22-20)}{20}\times 100$

=  $\frac{2}{20}\times 100$

$=\frac{200}{20}$

= 10%

percent change is 10% increase from last week to this week.
