Math question
6. marla swims twice a week. her equipment cost her $32.85 and she has a membership to the pool for $35 plus $3.50 per visit. she can walk to the pool, so transportation is free. how much will swimming cost her for the year?
(points : 1)
$431.85
$249.85
$396.85
$492.75

Swimming will cost $431.85 for Marla (per year).

Step-by-step explanation:

Hi, to solve this we have to calculate how many weeks are in a year:

If a year has 365 days, we have to divide it by 7 ( the number of days in a week)

So: 365 / 7  =52.14 = 52 weeks

Now, with the information given we have to multiply the number of weeks by the cost per visit multiplied by 2 ( because marla swims twice a week) and add the quipment cost ($32.85) and the membership cost ($35).

Mathematically speaking:

$3.50 x 2 x 52 w + $32.85 + $35 =

$364 + $32.85 + $35 =$431.85

In conclusion,   swimming will cost $431.85 for Marla (per year).

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
