Answer: 3 months
Step-by-step explanation:
Let x be the number of months and A and B the total costs for each service.
A = 45 + 65x
B = 80x
We want to know the months that would make A = B:
A = B, solve for x, months.
45 + 65x = 80x
45 = 15x
x = 3 months
After 3 months, Company A will be less expensive.
192.
We simply multiply 800 and 24% (0.24)
800(0.24) = 192
Yes they are. You can simplify 4:6 by dividing by 2 and get 2:3.
