Question

Math question please answer thanks!

Answer 1

Answer is C 41/20 inches

Monday 3/10
Tuesday twice as Monday: 3/10 * 2 = 6/10
Wednesday: 1/4
Thursday: 1/2
Friday: 2/5

Total: Monday + Tuesday + Wednesday+Thursday + Friday
= 3/10 + 6/10 + 1/4 + 1/2 + 2/5
= 6/20 + 12/20 + 5/20 +10/20 +8/20
=41/20

Answer 2

Monday = 3/10 = (3*2)/(10*2) = 6/20

Tuesday = twice on Monday = 2*(6/20) = 12/20

Wednesday = 1/4 = (1*5)/(4*5) = 5/20

Thursday =  1/2 = (1*10)/(2*10) = 10/20

Friday = 2/5 = (2*4)/(5*4) = 8/200 

Today = Sum of each day = (6/20) + (12/20) + (5/20) + (10/20) + (8/20)

= (6 + 12 + 5 + 10 + 8) / 20

= (41)/20

= 41/20 inches.

Option C.

Hope this helps.
