First convert 5 cans of dog food to a fraction
(5*3)/3 = 15/3
15/3 - 1/3 = 14/3
he uses 1/3 a can and so he then has 14 servings.
at the beginning of year 4, only 3 years have elapsed, the 4th year hasn't started yet, since it's at the beginning, so at the beginning of year 4 we can say only 4-1 years have elapsed.
![A=700\left( 1 + \frac{0.05}{1} \right)^{1\cdot 3}\implies A = 700(1+0.05)^3\implies A(4)=700(1+0.05)^{4-1} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill A(n)=700(1+0.05)^{n-1}~\hfill](https://tex.z-dn.net/?f=A%3D700%5Cleft%28%201%20%2B%20%5Cfrac%7B0.05%7D%7B1%7D%20%5Cright%29%5E%7B1%5Ccdot%203%7D%5Cimplies%20A%20%3D%20700%281%2B0.05%29%5E3%5Cimplies%20A%284%29%3D700%281%2B0.05%29%5E%7B4-1%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20A%28n%29%3D700%281%2B0.05%29%5E%7Bn-1%7D~%5Chfill)
Answer:
Final cost of the item is $19.55
Step-by-step explanation:
Expression representing the final cost of an item with original price = $p and discount = 15% will be,
Final cost = (p - 0.15p)
If the original price p = $23
By substituting p = 23 in the expression given,
Final cost after discount = 23 - (0.15)23
= 23 - 3.45
= $19.55
Therefore, final cost of the item is $19.55
