It is already rounded to the nearest tenth.
Answer:
Step-by-step explanation:
b+s=18
s=18-b
1.50 b+2.50 s=38
multiply by 4
6.00 b+10.00 s=152
divide by 2
3 b+5 s=76
3 b+5(18-b)=76
3 b+90-5 b=76
-2b=76-90
-2b=-14
divide by -2
b=7
s=18-7=11

Answer:
60 + 2.5n ≥ 150
2.5n ≥ 90
n ≥ 36 She must clean 90 tables to earn at least $150.
Step-by-step explanation:
She earns $2.50 for each table she cleans so n represents the number of tables she cleans. You add that to $60. At least must mean that the inequality has to be equal to or bigger than 60 + 2.5n.
Now we just have to solve, which I do for you above in the 'Answer' section.
I hope this helps you!! ^-^
