Answer:
Step-by-step explanation:
<u>Given:</u>
- Rate per hour = $6
- Number of hours = 5
- Tips = 15%
Lets the total amount of tabs = t
<u>We have inequality:</u>
- 6*5 + 0.15t ≥ 350
- 30 + 0.15t ≥ 350
- 0.15t ≥ 320
- t ≥ 320/0.15
- t ≥ 2133.33
2 a + b = 15.7
Since the sides are equal length, the equation is:
2 · 6.3 + b = 15.7
We can solve it:
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
