Answer:
a/1/$400
Step-by-step explanation:
240 divided by 12=20
20x10x2=$400
Answer:
33.33%
Step-by-step explanation:
We need to calculate the <u>unit selling price and cost of each cosmetics.</u>
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;
x = 1 cosmetic
since 360 = 12 cosmetic
cross multiply
12x = 360
x = 360/12
x = 30
Hence the unit cost price of the cosmetics will be Rs. 30
Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)
Selling price per unit = Rs. 40
Cost price per unit = Rs. 30
percent gain = SP-CP/CP * 100%
percent gain = 40-30/30 * 100
percent gain = 10/30 * 100
percent gain = 100/3
percent gain = 33.33%
Hence the percentage gain is 33.33%
Answer:
d
Step-by-step explanation:
its a triangle all sides are equal. so it would be d-60 degrees
If charge per day =x
and charge per mile =y
6x + 550y = 337
3x + 350y = 185
multiple the second equation by 2
6x+700y=370
subtract the first equation from this equation
150y=33
y=0.22
Now we plug the y back in to one of the initial equations to get the value of x
3x+350(0.22)=185
x=36
Charge per day is $36 and charge per mile is $0.22
