Answer:
Cost per kg = $2
Step-by-step explanation:
Given that:
7kg of soybean oil costs $4/kg
So 7kg of soybean oil will cost = 7 * 4 = $28
14kg of canola oil costs $1/kg
So 14kg of canola oil will cost = 1* 14 = $14
Now for mixture:
Quantity of (soybean oil + canola oil) = Cost of (soybean oil + canola oil)
7kg + 14kg = $28 + $14
21kg = $42
Now finding cost per kg of mixture:
Cost per kg = $42/21
Cost per kg = $2
i hope it will help you!

Answer:
Heyyyy!!
The answer is 66.9
please read the explanation... it will help... I promise
Step-by-step explanation:
Okay... Here we go...
The context mentions that the two quadrilaterals are similar... meaning their sides are proportional...
So... you basically have to find the scale factor...
(the math itself is easier than the explanation...
51/16 = 3.1875 (that is the number we multiplied the sides of quadrilateral FGHI to get quadrilateral JKLM...
so to get side JK all you have to do is multiply that scale factor by side FG... which after the use of a calculator results in 66.9 (i rounded, and used a calculator... lol)
but yeah... i hope this helps...
$70.88
x/67.5=5/100
cross multiply
100x=337.5
divide 100
x=3.375 or 3.38
67.50+3.38= 70.88
