the price of milk in 2013 was around $3.28 a gallon. This was eight times as much as you would have probably paid for a gallon o
Jlenok [28]

The cost of the milk is \fbox{\$\,0.41{\text{ a gallon}}} in 1950s.

Further explanation:

The price of milk in 2013 was around \$3.28 a gallon.

And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.

It is given that the price of milk in 2013 is \$3.28 a gallon.

Assume the price of milk in 1950 be \$x a gallon.

Now, given that 8 times of x is the price of milk in 2013.

Therefore, 8x is the price of milk in 2013 and also \$3.28 is the price of milk in 2013.

Equating 8x and  \$3.28 equal as both are the price of milk in 2013 as,

\begin{aligned}8x&=3.28\\x&=\frac{{3.28}}{8}\\x&=0.41\\\end{aligned}

Here, x is the price of milk in 1950.

Therefore, the cost of the milk is \fbox{\$\,0.41{\text{ a gallon}}} in 1950s.
