Explanation:

If Annabell works 4 hours and earns $100 that means for every hour she earns $25 so 25×4=100 so then multiply 25×6=15]

Answer 2

Answer: C. $150.

Explanation:

When two quantities x and y are directly proportional ,then the equation of direct proportion is given by :-

`(x_1)/(y_1)=(x_2)/(y_2)`

Given : Annabelle's total pay varies directly with the number of hours she works. If she works 4 hours, she earns $100.

Let
`x_1=100\ ;\ y_1=4 \ :\ x_2=x,\ y_2=6`, then we ahve

`(100)/(4)=(x)/(6)\\\\\Rightarrow\ x=(100*6)/(4)=150`

Hence, Annabelle earns $150 if she works 6 hours.
