Problem 1:
1) 3/5x-1 x 3/4=9/10
3x/5-1 x 3/4=9/10
2) 3x/5-1 x 3/4=9/10
3x/5-3/4=9/10
3) 3x/5-3/4=9/10
+3/4 +3/4
4) 3x/5=33/20
5) 5 x 3x/5= 5 x (33/20)
6) 3x=33/4
7) 3x=33/4
/3 /3
8) x=11/4
Problem 2:
1) 6/7+2/5x=-4/5
6/7+2x/5=-4/5
2) 6/7+2x/5=-4/5
-6/7 -6/7
3) 2x/5= --58/35
4) 5 x 2x/5= 5 x (--58/35)
5) 2x= --58/7
6) 2x= --58/7
/2 /2
x= --29/7
Depth of Hank descends = The point he reached - the point where he worked initially
= 57 - 10
= 47 ft
Hence, Hank descends 47 ft.
Answer:
$86
Step-by-step explanation:
first you gotta find the interest
4,600 * 1% = 46
so the interest is $46
then you add the interest and late fees together to get the payment for the month
46 + 40 = $86
your total cost is $86
a. The total cost is the sum of variable and fixed cost.
So the average cost of each hat is simply total cost divided by x:
ave cost = (2.12 x + 3000) / x
b. Total cost should be equal to Income:
2.12 x + 3000 = 2.75 x
Solve for x:
x = 4762 units
c. Profit is income minus total cost:
Profit = 2.75 x – (2.12 x + 3000)
1000 = 2.75x – 2.12 x – 3000
Solving for x:
<span>x = 6439 hats</span>
