The cost y, in dollars, to produce graphing calculators is given by the equation y = 48x + 2000, where x is the number of calculators produced. What is the cost to produce 2000 calculators?

zzr0ck3r · Answer

x = 2000

luigi0210 · Answer

Well you are looking for y, the total cost, so you have to plug in 2000 into the equation where x is the number of calculators

luigi0210 · Answer

so y=48(2000)+2000

wow it was that simple all along... wtf.. lol

how do you solve a problem like this

A truck rental company rents a moving truck one day by charging $39 plus $0.09 per mile. What is the cost of renting the truck if the truck is driven 160 miles?

luigi0210 · Answer

Do you know what the equation is?

anonymous · Answer

i was thinking about dividing .09 and 160...  then multipling that by 39? ehhh

anonymous · Answer

wasn't sure .. lol

luigi0210 · Answer

At least you gave it a try :P
but we have to use y=mx+b because this equation is linear

zzr0ck3r · Answer

actually its only linear when b = 0, otherwise it is affine. common misconception:)

luigi0210 · Answer

Oops, sorry wrong wording.. thanks for the correction

zzr0ck3r · Answer

its silly, I just learned that and found it strange that no teacher has told me that before:)
