Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 = 
( multiply both sides by 8 )
184 = k
y = 
← equation of variation
When x = 4 , then
y = 
= 46
Given Mr. Engle’s total income, I = $52,000 and total expenses, E = $53,800, solving for average difference between income and expenses per month:
(I-E)/12 = ($52,000 - $53,800)/12
(I-E)/12 = - $1,800/12
(I-E)/12 = -$150
This means that Mr. Engle’s expenses exceed his income by an average of $150 each month in the said year.
A) a customer would pay $1.60 for 1 pound of apples. (To solve, plug in “1” for “p” and find c))
B) 8.5 pounds of apples would cost $13.60. (To solve, plug in 8.5 for p and find c)
C) If a customer pays $5.20, they will have purchased 3.25 pounds of apples. (To solve, plug in 5.2 for c and solve for p)
Have a great day!
Answer:
Step-by-step explanation:
Basic Charge = $ 65
Rate per hour = $ 28
Number of hours = H
Rate for H hours = 28 *H = 28H
Equation:
65 + 28H ≤ 250
