Answer: $28
Step-by-step explanation:
The person bought 6 cakes for $8 which reduces his money by:
= 6 * 8
= -$48
He then sells them for $10 each so the money made was:
= 10 * 6
= $60
He then buys 8 more for the same price which will reduce his money by:
= 8 * 8
= -$64
He sells these 8 for $10 so the money made was:
= 8 * 10
= $80
Total money left is therefore:
= 60 + 80 - 48 - 64
= $28
Answer:
3x^2 - 8x + 4.
Step-by-step explanation:
36x^3 - 96x^2 + 48x
Dividing by 12 term by term:
= 3x^2 - 8x + 4.

Answer: it will take 25 months
Step-by-step explanation:
Let x represent the number of months that it will take for the cost of both plans to be the same.
Cell phone Plan A costs $70 per month and comes with a free $500 phone. This means that the total cost of x months with plan A would be
70 × x = $70x
Cell phone plan B costs 50 per month but does not come with a phone. If you buy the 500 phone and choose plan B, then the total cost of x months with plan B would be
500 + 50 × x = 500 + 50x
To determine the number of months until your cost is the same as Plan A's, we would equate both costs. It becomes
70x = 500 + 50x
70x - 50x = 500
20x = 500
x = 500/20 =25
