Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item.
The net income formula:
y= (5 - 4)x - 120
(5-4)= contribution margin per unit sold (x)
120= fixed costs
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 120 / 1
Break-even point in units= 120 units
Prove:
y= 1*120 - 120
y= 0

Answer:
108, 77
Step-by-step explanation:
Let x represent the larger part. Then ...
x + (x -31) = 185
2x = 216
x = 108
x -31 = 77
The two parts are 108 and 77.
B. 1/4
C. 1/8
D. 1/16
E. 1/32
Probability helps us to know the chances of an event occurring. The probability that all four pennies will be tails is (1/16).
Probability helps us to know the chances of an event occurring.
The probability of a penny getting a tail is 0.5 or (1/2), therefore, the probability of four penny getting a tail can be written as,
Hence, the probability that all four pennies will be tails is (1/16).

Step-by-step explanation:
Holly earns $6 per hour for babysitting and $7 per hour for chores, meaning she earns more per hour when doing chores.
The question is about comparing the unit rates between Holly's babysitting job and her chore earnings. Unit rate refers to the amount of money earned per hour. Here's how we calculate it:
So, Holly earns more per hour when she is doing chores compared to when she's babysitting.

Answer:
The total income is 257,250
Step-by-step explanation:
The initial value of salary is 36,000 a year with an increase of 250 every year. Next is presented the salary table of each year:
Year Salary
To have the total income you have to sum all the value of the seven years.
Total income = 36,000 + 36,250 + 36,500 + 36,750 + 37,000 + 37,250 + 37,500 = 257,250 is the total income for the 7 years.
