2. A long distance phone company has a monthly fee of $7.95 and charges a rate of $0.05 per minute. Another long distance company has a monthly fee of $9.95 and charges a rate of $0.03 per minute. At how many minutes would the two companies have equal charges?

15. A boat travels 30 miles upstream in 4 hours. The trip downstream takes 2.5 hours. Find the rate of the boat in still water.

20. Solve: 5x^2 - 10x = 0

50. (x-1)(x^3 + x^2 + x) =?

Thanks

7.95 + .05x = 9.95 + .03x

Solve for x.

15. Can't help here.

20. 5x(x-2) = 0

x = 0 or 2

50. Do you want to factor or multiply?
