Determine the unit rate for 1 bag of chips if 5 bags cost $6.25; the proportional relationship is described by 5y=$6.25x.(1 point)
Responses
A. $1
B. $0.80
C. $31.25
D. $1.25
To determine the unit rate, we need to divide the total cost by the number of bags. So, the unit rate for 1 bag of chips is $6.25/5 = $1.25.
Therefore, the correct answer is D. $1.25.
To determine the unit rate for 1 bag of chips, we need to find the value of y when x is equal to 1 in the equation 5y = $6.25x.
First, let's find the value of y when x is equal to 1:
5y = $6.25(1)
5y = $6.25
y = $6.25 / 5
y = $1.25
So, the unit rate for 1 bag of chips is $1.25.
Therefore, the correct answer is D. $1.25.
