Answer:
y = 5
x = 10
Step-by-step explanation:
Remember your 30 60 90 triangle rules.
The 5√3 would equal x√3, so x would equal 5.
The x for the hypotenuse is 2x, so 2(5) is 10.
The y is the x for a 30 60 90 triangle, so y = 5.
Hello! So, we could set up a proportion to solve this, because the price and CPI increased at the same rate. Let's set it up like this: 34.6/82.4 = 0.75/x. This is because we know the prices from the 1960's, but we don't know the gallon of milk price in 1980, and we line them up like that to make sure we get the proper answer. Cross multiply the values in order to get 34.6x = 61.8. Now, divide each side by 34.6 to isolate the variable. x ≈ 1.7861 and other numbers behind it or 1.79 when rounded to the nearest hundredth. The price for a gallon of milk in 1980 was about $1.79.
Since it's a local (a possible branch) hardware store, it's POSSIBLE BUT VERY UNLIKELY:
PROOF: Assume 100 clients/day are buying from this store, that means,
3,600 customer a month or 43,200 clients a year. The one-millionth customer will occur after 1,000,000/43,200 = 23 years. or it will be after 46 years if the average customer is 50/day. So it is possible but MOST UNLIKELY
[Figured it out themselves (see comments), just putting this here so it stops showing up as unanswered]
