Deandre's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Deandre $5.75 per pound, and t

Ludmilka [50]

Type A cost $5.75 per pound

Type B cost $4.25 per pound.

Set up 2 equations:

A. + B = 174 pounds

5.75A + 4.25B = 880.50

Rewrite the first equation as A= 174 - B

Replace A in the second equation:

5.75(174-B) + 4.25B= 880.50

Use distributive property:

1000.50 - 5.75B + 4.25B = 880.50

Combine like terms:

1000.50 - 1.5B = 880.50

Subtract 1000.50 from both sides:

-1.5B = -120

Divide both sides by -1.5:

B = -120 / -1.5

B = 80

They used 80 pounds of type B

Subtract B from the total used to find type A:

174 - 80 = 94

They used 94 pounds of type A

Divide the sum of 3/4 and −4/7 by their difference

Dafna11 [192]

Answer:

5/37.

Step-by-step explanation:

Sum:

3/4 + -4/7

= 21/28 - 16/28

= 5/28

Difference:

3/4 - (-4/7)

= 3/4 + 4/7

= 21/28 + 16/28

= 37/28.

Dividing:

5/28 / 37/28

= 5/28 * 28/37

= 5/37.

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points

The access code for a cars security system consist of four digits the first digit cannot be 1 and the last digit must be odd how

Katena32 [7]

So we have 10 numbers 0 - 9
0 1 2 3 4 5 6 7 8 9
The first digit cannot be 1
therefore there are 9 possibilities
0 2 3 4 5 6 7 8 9

digits 2 and 3 can be numbers 0 through 9
therefore there are 10 possibilities for digits 2 and 3
digits 2 and 3 are a total of 2 digits
and the last digit must be odd so there are 5 possibilities -> 1 3 5 7 9
so
$9 * 10^2 * 5 => 9 * 100 * 5 => 45* 100 = 45,000$
