Answer:
C. 4.2 pounds Brand A. 0.8 pounds Brand B
Step-by-step explanation:
How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
Let the number of pounds for Brand A = x
Let the number of pounds for Brand B = y
Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound.
$7 × x + $5.40 × y = $6.75 × 5
7x + 5.40y = 33.75.......Equation 1
x + y = 5 .......Equation 2
x = 5 - y
7(5 - y)+ 5.40y = 33.75
35 - 7y + 5.40y = 33.75
35 - 33.75 = 7y - 5.40y
= 1.25 = 1.6y
y = 1.25/1.6
y = 0.78125 pounds.
Approximately to the nearest whole number, Brand B = 0.8 pounds.
x = 5 - y
x = 5 - 0.8 pounds
x = 4.2 pounds
Brand A = 4.2 pounds
The ratio would be 1:4 so your cousins ate 8 slices.

Step-by-step explanation:
Answer:
He began with 14 please mark brainliest
Step-by-step explanation:
13-6 equals 7
7 times 2 equals 14
So a-47=b
so total value =113 times 1,000,000=113,000,000=a+b
subtitute a-47=b into equation
a+a-47=113,000,000
add 47 to both sides
2a=113,000,047
divide both sides by 2
$56,500,023.5=a or <u>roughly</u> 56.5 million
a-47=b
56,500,032.5-47=b
56,499,976.5=b
so 56,500,023.5=a
56,499,976.5=b
