Shonna skateboarded 40 minutes on Monday, 80 minutes on Tuesday and 60 minutes on Wednesday.

Step-by-step explanation:

Given,

Total time spent on skate boarding = 3 hours

1 hour = 60 minutes

3 hours = 60*3 = 180 minutes

Time spent on skate boarding = 180 minutes

Let,

Time spent on skate boarding on Monday = x

Time spent on Tuesday = 2x

Time spent on Wednesday = \frac{x+2x}{2} = \frac{3x}{2}

According to given statement;

x+2x+\frac{3}{2}=180

Taking LCM on left side;

\frac{2x+4x+3x}{2}=180\\\frac{9x}{2}=180

Multiplying both sides by 2

2*\frac{9x}{2}=180*2\\9x=360

Dividing both sides by 9

\frac{9x}{9}=\frac{360}{9}\\x=40

Time spent on Monday = x = 40 minutes

Time spent on Tuesday = 2x = 2(40) = 80 minutes

Time spent on Wednesday = \frac{3x}{2} = \frac{3(40)}{2} =\frac{120}{2} = 60\ minutes

Shonna skateboarded 40 minutes on Monday, 80 minutes on Tuesday and 60 minutes on Wednesday.

= $82.50

So, your new monthly salary would be = $1,375.00 + $82.50

52% of ______ days is 13 days.
abruzzese [7]
'of' in mathematics means multiplication
'is' in mathematics means equal

52% * x = 13

52/100 * x = 13

0.52x = 13

x = 13/0.52

x = 25

52% of 25 days is 13 days.
