Answer:
1) $350
2) 55°
3) $300
Step-by-step explanation:
1) The total cost is the cost of the appointment plus the cost of the repair work. The appointment costs $50. The repair work costs $120 per 2 hours. So the total cost is:
C = 50 + (120/2) t
C = 50 + 60t
For 5 hours of work, the cost is:
C = 50 + 60(5)
C = 350
It costs $350.
2) The temperature starts at 70°. It drops 10° in 4 hours. So the temperature after t hours is:
T = 70 + (-10/4) t
T = 70 − 2.5t
After 6 hours:
T = 70 − 2.5(6)
T = 55
The temperature is 55°.
3) Jennie's total pay is her weekly pay plus her commissions. If her commission is x% of her sales, then her pay is:
P = 250 + (x/100) S
When her sales is $1000, her pay is $275.
275 = 250 + (x/100) 1000
275 = 250 + 10x
25 = 10x
x = 2.5
So her pay is:
P = 250 + (2.5/100) S
When S = $2000:
P = 250 + (2.5/100) 2000
P = 250 + 50
P = 300
Her total pay is $300.
Answer: B
Step-by-step explanation:
When you factor an expression, you want to take out a factor of the numbers and variables.
Since this expression is a bit hard to factor as itself, we can FOIL the answers to see the correct expressions.
(4x-5)(4x-5)
16x²-20x-20x+25
16x²-40x+25
Answer: 1/2
Step-by-step explanation:
Let the missing fraction be x
x + 1/16 = 3/2
Make x the subject by subtracting both sides by 1/16
x = 3/2 - 1/16
x= 24 - 16/16
= 8/16; divide through by a common value of 8
x = 1/2
I hope this helps.
