Detailed breakdown:
For beef, we calculate 12 * 8 (since 25 * 8 gives 200)
Thus, beef totals = 96
For chicken, we find 8 * 8 (again, because 25 * 8 equals 200)
Hence, chicken totals = 64
For pasta, the calculation is 5 * 8 (as 25 * 8 = 200)
Thus, pasta totals = 40
Conclusion- C] There are 32 extra students preferring beef over those who choose chicken
Answer:
a) The first inequality is 100 + 55x > 150 + 51x;
b) The final inequality results in x > 12.5
c) Sal's mother will need to use the second phone for at least 13 months.
Step-by-step explanation:
a) Let x represent the number of months.
1. The first phone is priced at $100, with a monthly fee of $55 for unlimited use, leading to a total cost of $(100 + 55x) for x months.
2. The second phone costs $150 with a monthly fee of $51 for unlimited use, resulting in a total of $(150 + 51x) for x months.
3. For the second phone to be cheaper, we set up the inequality:
150 + 51x < 100 + 55x
which simplifies to
100 + 55x > 150 + 51x
b) Now solve this:
55x - 51x > 150 - 100
4x > 50
so x > 12.5
c) This means Sal's mother has to retain the second phone for at least 13 months (since x > 12.5).
Solution
The number of weeks in a year is 52 weeks
In a typical year, where each flea treatment lasts 4 weeks, Jim's dog would receive
Conversely, during especially bad flea years, when treatments only last for 3 weeks, Jim's dog would need
So in a year, Jim's dog would need 17- 13 =4 extra treatments.
4 treatments at 3 weeks each total 4×3 =12 weeks of additional treatment
