Answer:
Case (c) has the lowest unit price and is thus the best buy.
Step-by-step explanation:
Example: (a) The unit price is the price paid divided by the weight:
$0.50
------------ = $0.2857/oz, or (to 2 decimal places) $0.29/oz
1.75 oz
(b) $1.00/(6 ounces) = $0.17/oz
(c) $1.88/(12 ounces) = $0.16/oz
Case (c) has the lowest unit price and is thus the best buy.
The correct answer is:
A. 14x+6y= 10
-14X-35y=77
Further explanation:
One method of solving system of linear equations in two variables is elimination method. In this method, the co-efficient of one variable have to be equated so that variable can be removed to get the value of other variable.
Given equations are:
As we have to eliminate x, then the co-efficient of x will be equated. For this purpose both equations will be multiplied with some constant.
So,
multiplying equation one with 2
Multiplying equation 2 by -7
So,
The correct answer is:
A. 14x+6y= 10
-14X-35y=77

Answer: 44) 25 45) 4 46) 27
<u>Step-by-step explanation:</u>
Filling in the Venn Diagram (from left to right, including outside of circles):
S only = 14
S ∩ F = 1
F only = 26
S ∩ B = 7
S ∩ B ∩ F = 4 --> answer to #45
F ∩ B = 14
B only = 10
<u>(S ∪ F ∪ B)' = 25</u> --> answer to #44
Total = 100
46) F total - (F ∩ B)
= 45 - 18
= 27
Answer:
43/12
