Answer:
<em>The man paid $200 for the cow</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's call:
x = price of the cow
y = price of the horse
The man bought the cow and the horse for $500, thus
x + y = 500 [1]
The cow was sold at a profit of 10%, thus:
Sale price of the cow= 1.1x
The horse was sold at a loss of 10%, thus:
Sale price of the horse= 0.9y
The total operation was a 2% loss, i.e. 0.98*500=490. Thus, we have:
1.1x + 0.9y = 490 [2]
From [1]:
y = 500 - x
Substituting in [2]:
1.1x + 0.9(500 - x) = 490
Operating:
1.1x + 450 - 0.9x = 490
0.2x = 490 - 450 = 40
x = 40/0.2
x = 200
The man paid $200 for the cow
Answer:
0
Step-by-step explanation:
3x+2=2
or, 3x=2-2
or, x=0/3
:. x=0
how long is |MN| when you measure it and do you know anything about the length of |NO| and |OP|?
assuming |MN|= 7.7 ; |NO|= 4.7 ; |MO|= 5.5:
o²= m²+n²
= 4.7²+5.5²
=52.34
o=V52.34
≈7.23
Answer:
The cost of 16 oz of granola should be $16.16
Step-by-step explanation:
Given that,
The cost of 3 oz of granola is $3.03
We need to find the cost of 16 oz of granola..
As 3 oz = $3.03
1 oz = (3.03/3) = $1.01
The cost of 16 oz will be :
16 oz = 16×1.01
= $16.16
Hence, the cost of 16 oz of granola should be $16.16.
Answer:
5%
Step-by-step explanation:
2000/40000 = 0.05
All you do is divide both numbers and you'll get the decimal form which in this case is 0.05 which means 5%.
