Can anyone help me with equations?
yes
Well we all could if you would ask a question.
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
sorry
its ok
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..
if you wanted to spend exactly $37.50 on your cell phone bill, how many additional minutes will that allow you to use
woah now.. did u solve for the first one?
yep c=60
good job
ok so now onto the seond one..
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
25m
no no no...
oh i'm mean m=25
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?
m=25
correct
anyothers? i have to leave in 7 mins so u might as well ask me now if u want something answered
one more
one summer sangeeta had a paper route and a babysitting job, she made twice as much money babysittin as she did delivering papers. altogether she made $800 that summer. what equation can you use to find how much sangeeta earned delivering papers?
d for delivering b for babysitting
so twice more is times two for babysitiing so 2b and then u add d so 2b+d then the two jobs made 800 soo 2b+d=800
so she makes around 266.66$ in one paper route
yep
alright
