5 ounce can is better to buy
<h3><u>Solution:</u></h3>
Given that 5 ounce can of tuna cost $0.90 and a 12 ounce can of tuna costs $2.40
To find: which is better to buy
To find out which one is the better buy we have to find out what the unit price of both cans
To find a unit price you divide the ounce by the cost.
<h3><u><em>
5 ounce can of tuna cost $0.90:</em></u></h3>
cost of 5 ounce can = $ 0.90
Thus cost of 1 ounce is found out by:
![\text {cost of } 1 \text { ounce }=\frac{0.90}{5}=0.18](https://tex.z-dn.net/?f=%5Ctext%20%7Bcost%20of%20%7D%201%20%5Ctext%20%7B%20ounce%20%7D%3D%5Cfrac%7B0.90%7D%7B5%7D%3D0.18)
Thus cost of one ounce is $ 0.18
<h3><u><em>
12 ounce can of tuna costs $2.40:</em></u></h3>
cost of 12 ounce can = $ 2.40
Thus cost of 1 ounce is found out by:
![\text {cost of } 1 \text { ounce }=\frac{2.40}{12}=0.2](https://tex.z-dn.net/?f=%5Ctext%20%7Bcost%20of%20%7D%201%20%5Ctext%20%7B%20ounce%20%7D%3D%5Cfrac%7B2.40%7D%7B12%7D%3D0.2)
Thus cost of one ounce is $ 0.2
Thus on comparing unit price of 5 ounce can and 12 ounce can,
we can see clearly that unit price of 5 ounce can costs less than 12 ounce can
Thus 5 ounce can is better to buy
Take into account that x represents the number of decades after 1950. Moreover, consider that -0.5x is a decrease in the values of y, each decade.
Then, you can conclude that each decade, that is, every 10 years, the shoreline reduces 0.5 feet.
Hnece, you have:
The shoreline is reduced by 0.5 foot every 10 years
Y=4/3x+1/3
Y=Mx+b is slope intercept form
