Answer:
1.25, 40
1.6, 30
Step-by-step explanation:
First, we'll state that the lbs of candy worth $1.25 is A and the lbs of candy worth $1.6 is B.
We write the equations: A + B = 70, (This is the lbs)
and, 1.25A + 1.6B = 1.4(70) (This is money)
Next, choose an equation you want to solve for, in this case, I'll choose A.
In the lbs equation, subtract A from both sides, A - A + B = 70 to get B = 70 - A
Now substitute this equation into the money equation.
1.25A + 1.6(70 - A) = 98
1.25A + 112 - 1.6A = 98
-0.35A = -14
multiply by negative
0.35A = 14
divide
A = 40
Then, you substitute 40 into the lbs equation, 40 + B = 70, making B = 30! Done!
