Answer:
Step-by-step explanation:
Let x represent the number if months it will take for the total costs of both plans to be the same.
The first plan has $50 signup fee and costs $20 per month. This means that the total cost of using the first plan in a month would be
20x + 50
The second plan has $30 sign up fee and cost $25 per month. This means that the total cost of using the first plan in a month would be
25x + 30
For the costs to be the same,
20x + 50 = 25x + 30
25x - 20x = 50 - 30
5x = 20
x = 20/5 = 4
The costs would be the sane after 4 months. The cost would be
20 × 4 + 50
= $130

Answer: 40 percent
Step-by-step explanation: real value = 1.5 liters ,estimated value = 2.1 liters.
Percentage student's estimate = (difference in estimate/ real value) × 100
Difference in estimate = 2.1-1.5 = 0.6
Real value = 1.5
Percentage student's estimate = (0.6/1.5)×100 = 0.4×100 = 40 percent
