Answer:
first one is 41 i think and the second is 30 for sure
Step-by-step explanation:
<span>n >= 1125
First, make an equation to express the money raised after expenses.
55n - 15n + 10000 = m
The above expression can be read as "55 dollars per running is raised, but 15 dollars is spent per running to support them. Plus we get 10000 as a constant regardless of how many runner we have." Now convert that to an inequality for at least 55000 to be raised.
55n - 15n + 10000 >= 55000
Now solve for n
55n - 15n + 10000 >= 55000
40n + 10000 >= 55000
40n >= 45000
n >= 1125
So there needs to be at least 1125 runners in order to meet the goal of $55,000.</span>
All sides are together. Basic question actually.
5y+7x+4z this is the simplified answer .
Answer:
12 + 2w > 40
w > 19
Minimum value of w is 20 feet.
Step-by-step explanation:
Consider the provided information.
Sharon has at most $25 to spend on her sister's birthday gift.
That means Sharon can spend not more than $25.
She already bought a knitting machine for her, which cost $14.99.
She would also like to get her sister some skeins of yarn to go with it. Each skein costs $2.75.
Let y represent the number of skeins of yarn.
Thus, the required inequality is:
Now solve the above inequality.
Skeins must be an integer.
Hence, the most number of skeins Sharon can afford to buy is 3.
ona wants to bake at most 30 loves of banana bread and nut bread for a bake sale. Each loaf of banana bread sells for $2.50 , And each loaf of nut bread sells for $2.75. Cora wants to make at least $44. Write a system of inequalities to model the situation
