Answer:
at least $450
Step-by-step explanation:
Let the amount she has in bank before depositing be x
If she had at least $550 in the bank after depositing, then;
x + 100 ≥ 550
Get the initial amount in bank
x ≥ 550 - 100
x ≥ 450
Hence the amount she has in the bank originally was at least $450
Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
Answer:
7y+6
Step-by-step explanation
You have to do 2 times y first. That is 2y. Then you have to add 2y plus 5y, which is 7y. 7y plus 6 equals 7y+6.
Rs 100 of the average total cost is made up of variable costs.
Step-by-step explanation:
Given:
Number of output the firm produces= 7 units
Average cost of the output= Rs. 150
fixed factors of production = Rs.350
To Find:
How much of the average total cost is made up of variable costs=?
Solution:
we know that,
Average total cost= total cost/ number of output units produced
substituting the values, we get
Total cost= 1050
we know that Total fixed cost = 350
Total cost = Total fixed cost + Total variable cost
plug in the known values.
1050= 350 + Total variable cost
Total variable cost = 1050-350
Total variable cost =700
For 7th unit 
= 100
