f(7)=140
Step-by-step explanation:
Answer:
Incremental cost of buying = $2.50
Step-by-step explanation:
Cost per unit;
Direct materials = $10.30
Direct labor = $24.30
Overhead = $16.30
Total Overhead cost = 10.30 + 24.30 + 16.30
= $50.90
Where the item is purchased,
Total cost = $46.88 + (40% × 16.30)
= $46.88 + $6.52
= $53.40
Cost difference = $53.40 - $50.90
= $2.50
There is an incremental cost of buying. This amounts to $2.50
Median is the number in the middle when all the numbers are put in order.
Let's do that first.
30 52 61 65 68 68 69 75 78 85
Now if there's 10 numbers, 2 numbers are in the middle.
By counting in 4 on both sides, we know the two numbers are both 68, so 68 is the median.
25×7.25=181.25
443.75-181.25=262.5
262.5÷25=13.125
$13.13
2.34$ because .2% of 1,215.60 is 2.431
