Answer:
Sabrina bought 3 pounds of bananas.
Step-by-step explanation:
Given equations are:
a + b = 8 Eqn 1
0.95a + 1.10b = 8.05 Eqn 2
As we have to find the number of pounds of bananas bought, we will eliminate the variable a from the equation.
Multiplying Eqn 1 by 0.95
0.95(a+b=8)
0.95a+0.95b=7.60 Eqn 3
Subtracting Eqn 3 from Eqn 2
(0.95a+1.10b)-(0.95a+0.95b)=8.05-7.60
0.95a+1.10b-0.95a-0.95b=0.45
0.15b = 0.45
Dividing both sides by 0.15
Hence,
Sabrina bought 3 pounds of bananas.

Answer:
the cost of each bag at chips is $0.75
the cost of bottle is $1.50
The cost of gallon of milk is $3.50
Step-by-step explanation:
Let us assume the cost of each bag at chips be x
For the cost of bottle it would be 2x
And for cost of gallon of milk be 2x + 2
The total cost is $22.50
Now the equation would be
3(2x +2) + 5(2x) + 6x = $22.50
6x + 6 + 10x + 6x = $22.50
22x = $16.50
x = $0.75
So cost of each bag at chips would be $0.75
For the cost of bottle be
= $0.75 × 2
= $1.50
And, for the cost of gallon of milk be
= 1.50 + 2
= $3.50
Answer: 503.8
Step-by-step explanation: 503.782 is the original fraction. To round up the number has to be 5, 6, 7, 8, or 9. The number in the hundredths place is 8. so that means the number in the tenths place can be moved up to 8 since 7+1=8.
8.49 \2 = 4.245
So your answer would be 4.245
