Answer: $1980
Step-by-step explanation:
First, let’s find out her monthly sales by adding up the 4 weekly sales.
2400+ 3200 + 5200 + 1200 = 12000
Next, find the amount of commission on 12000
4%/100=0.04
12000*0.04=480
Next add her commission to her monthly wage of 1500
1500+480=1980
We know in these kind of triangles that have a 90 degrees angle, we can do:

so the first question:

and then:

so , when you want to rationalize , usually you must multiply the irrational factor as 1:

so , now multiply:

in the next question,we know negative numbers in radical don't have any solution so 2 is correct,
