The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60
Therefore, our answer is correct.
Area of road =70*50=3500
3500*2=7000 because it has cross road
6*6=36
7000-36=6964
6964*5.50=38302
Tan(A) = Opp/Adj = CB / AC = 12/9 = 4/3

Hi there!
To solve this problem, we need to multiply the cost of each book by the amount of books Wally bought.
$19.50 × 9 = $175.50
So, the total amount payed was $175.50.
Hope this helps!
