Answer: Plan A is less expensive for 50 minutes. About $6 less than Plan B

At 200 minutes, both plans cost $24

Step-by-step explanation:

1.) Look at the numbers for minutes going across the bottom from left to right. Find 50. Follow the grid line up to where the blue line crosses it. (The blue line is lower than the red line so the cost is less.) Look at the numbers on the cost scale to verify the difference if someone asked. Plan A costs $6. Plab B costs $12 for 50 minutes.

2.) Look at where the Red and Blue lines intersect. That is where the plans cost the same amount of money for the same amount of minutes. Follow the grid line down from that point to find the number of minutes.

$Question$

Alice skates 2/5 mile in 1/5 hour. Elizabeth skates 2/3 mile in 2/9 hour. How far did elisabeth escape in in 1 hour?

Answer:

The Correct Answer is $\frac{8}{9}$

Complete the multiplication and the equation becomes

$\frac{2}{9}$ + $\frac{2}{3}$ = ?

The two fractions now have like denominators so you can add the numerators.

$\frac{2+6}{9}$ = $\frac{8}{9}$

Therefore, The Answer Is $\frac{8}{9}$

Hope this helps!
