Answer:
C.
x > 22
Step-by-step explanation:
Deena has already taken 126 calls
She takes 7 calls per hour ( think slope)
y = mx+b
y = 7x+126
She needs to take at least 280 calls. So what she does must be greater than 280
280 <7x+126
We need to isolate x. The first step is to subtract 126 from each side
280-126 < 7x + 126 -126
154 < 7x
Next, we divide by 7 on each side
154/7 < 7x/7
22 < x
5 and 10 because 5x10 = 50 and 5+10 = 15
Answer:
(86-75)= 11
now 11/75=0.147
hence 0.147 x 100= 14.7%.
therefore the percentage of workers needed to produce 86 cases is 14.7%
Step-by-step explanation:
step 1: We subtract the averages.
step 2: we devide the result in step one by the old average.
step 3: we multiply the result in step 2 by 100%.
They purchased 40 uniforms. If you divide 3,000 by 40, you'll find the amount that they paid for each uniform.
3,000 divided by 40 is 75. They paid $75 per uniform. To find the difference between the original price and the returned money, subtract 40 from 75.
75 minus 40 is 35. The difference between what they paid for each uniform and what they got for each return is $35.
