Oduvanchick [21]

Answer: Hi!  So, 1 lbs per week are equal to 7.4999e-7 kilograms per second. We can use this to convert lbs per week to kg per second. 721 x 7.4999e-7 = 0.000540741!

andreev551 [17]

Answer:

1) $250

2) $200 + $50x

$200 (start up fee) + $50 * ( 1 month ) = $200 + $50 = $250

2)

$200 (start up fee) + $50 * ( x months ) = $200 + $50x

Hope this helps :)
