Answer:
$26.25
Step-by-step explanation:
We know that I = Prt where I = Interest, P = Principal, r = rate (as a decimal) and t = time (in years). Therefore:
I = 750 * 0.035 * 1 = $26.25
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

The square area is 6*6=36
For the two triangles, the area is base*height/2 = 6*3 = 18.
So the total area is 18+36+18=72
Answer:
Option D : $780 is the correct answer.
Step-by-step explanation:
Given expression is:
E = $500 + $7x
We will put all the values of given options to check.
A. Putting 430 in given expression
430 = 500 + 7x
430 - 500 = 7x
-70 = 7x
As the number of items sold cannot be negative, therefore, this option is not correct.
B. 530 = 500 + 7x
530 - 500 = 7x
30 = 7x
x = 4.3 (By dividing both sides by 7)
Which is not a whole number.
C. 680 = 500 + 7x
680 - 500 = 7x
7x = 180
x = 25.71
Which is also not a whole number.
D. 780 = 500 + 7x
780 - 500 = 7x
280 = 7x
7x = 280
x = 40
Which is a whole number.
Hence,
Option D : $780 is the correct answer.
Irrational because it keeps going on and on but doesn’t repeat
