Answer:
The cost of a candy bar is $0.75.
Step-by-step explanation:
With the provided first sentence preceded along the lines, 'total cost of a candy bar and a bag of chips is $1.70.'
--Intially, determine the quotient of 1.70 and the two quantities.
+ Result should be 0.85
Thus symbolizing .85 is the valid price of a candy bar and a bag of chips.
------------------------- Although, we are not done. -----------------------------------
Let's take the second sentence into account.
"If the cost of a candy bar and 2 bags of chips is $2.45, what is the cost of a candy bar?"
Determine the sum of .75 and (.85*2)
Alert: .75 came from subtracting 10 from the intial .85
Thus the sum is $2.45, which was stated earlier as the cost of a candy bar and 2 bags of chips.
