Answer:
2.6 pounds of apples; 1.2 pounds of bananas
Step-by-step explanation:
A = pounds of apples and B = pounds of bananas
The total weight is 3.8 pounds, so:
A + B = 3.8
Apples are $1.90 per pound and bananas are $0.75 per pound, and the total cost is $5.84, so:
1.90A + 0.75B = 5.84
We can solve the system of equations using either elimination or substitution.
Using substitution:
1.90A + 0.75(3.8 - A) = 5.84
1.90A + 2.85 - 0.75A = 5.84
1.15A = 2.99
A = 2.6
B = 3.8 - A
B = 1.2
Step-by-step explanation:
According to PEMDAS parentheses are first.
2(6+1) can be simplified to 12+2.
5(3+2) can be simplified to 15+10
Add these two together.
12+2+15+10
14+15+10
29+10
y=39
Note - when you have something like this in math 2(6+1) it means you need to do 2 x 6 and 2 x 1

Divide 3 apples by $2.50 to get the unit price, $1.20 (The constant of proportionality)
Then multiply 12 apples by the constant ($1.20)
Your final answer should be $14.40
