A teacher’s salary was $3300 after she had received an increase of 10%. Calculate the teacher’s salary if she has received an increase of 20% instead.
First, we need to find the starting salary. Let the starting salary be s. Since 10% as a decimal is 0.10, We're given:
s*(1.10) = 3300
1.10s = 3300
To solve for s, we type this equation into our search engine and we get:
s = 3000
The problem asks for the new salary if the teacher's starting salary was increased by 20%. 20% as a decimal is 0.20, so we have:
3000(1.2) = $3,600
