Generic sugar which costs $2.23/kg is made by combining brand X sugar which costs $1.18/kg with brand Y sugar which costs $3.98/kg. Find the number of kg of brand X sugar and brand Y sugar required to make 40 kg of generic sugar.

Answers

Answer:

X = 14 kg

Y= 7 kg

Step-by-step explanation:

LET X and Y equal the amounts of brand X and Y

X = kg of brand X

Y = kg of brand Y

we know:

1) X + Y = 21 (kg)

2) 1X + 4Y = 2(X + Y) (This is the cost/kg * amounts for total cost)

Coefficients 1,4,2 are the cost/kg)

substitute eq. 1 (X+Y), = 21 into right side of equation 2

1X + 4Y = (21)*2

use elimination to solve 2 equations

X + Y = 21

X + 4Y = 42 (now subtract, note: I wrote the 1X as just X)

------------------

0 -3Y = -21 OR Y = 7 kg so X = (21-7) OR X = 14 kg

Evaluate a + b if a = 0 and b = -20

Answers

The answer is -20.

The number 0 has no value to it. So we would be adding nothing.0+-20=-20Even if we did add 0+20 the value would still be -20

Now if we added 1+-20 would be -19. We would need exactly 20+-20 to get out of the negitives.

Answers

Answer:

382. 5

Step-by-step explanation:

Answer:

26.74 ($) or change currency sign to suit.

Step-by-step explanation:

Binoculars Mark up = 10x 1.45 = 14.50

Sales tax = 14.5 x 1.085 = 15.7325

Total cost per Binocular = 15.73 ($,)

Bird Guide Mark up = 7 x 1.45 = 10.15

Sales Tax = 10.15 x 1.085 = 11.01275

Total cost per Bird Guide = 11.01 ($)

One of each is found by addition.

15.73 + 11.01 = 26.74 ($) or change currency sign to suit.
