A cell phone company offers a plan. The cost of this plan is $30 per month, plus $0.30 for each extra minute used that is not included in the plan. The cost for cell phone use according to this plan is C = 30 + 0.30m, where C is the total cost and m is the number of additional minutes used. (Taxes are already included in these costs and DO NOT need to be calculated or added) a) How much would it cost in a month if you used an extra 100 minutes in addition to the plan? EQUATION QUESTION

well...C=30+0.30m m is minutes. so if he used 100 minutes. u plug 100 in for m so then you woould solve this: C=30+0.30(100) tell me what you get when u solve it out..

well if your equation is C=30+0.30 and C is the total amount. in this case your total amount is 37.50 so u put 37.50 in for C giving u the equation: 37.50=30+0.30m solve and tell me your answer

  • karatechopper
no no no...
anonymous
  • anonymous
oh i'm mean m=25
karatechopper
  • karatechopper
37.50=30+0.30m your first step is to subtract 30 on both sides which will give u 7.50=0.30m then u divide by 0.30 on both sides... what do u get?

karatechopper
  • karatechopper
d for delivering b for babysitting
karatechopper
  • karatechopper
so twice more is times two for babysitiing so 2b and then u add d so 2b+d then the two jobs made 800 soo 2b+d=800
