The number of items (N) that can be purchased for a given amount of money is inversely proportional to the cost (C) of an item.

mars1129 [50]

Answer:

436 items

Step-by-step explanation:

When a quantity A is inversely proportional to another quantity B, we can write:

$A=\frac{k}{B}$

Where k is the proportionality constant [that we need to find]

For this problem, we can write the ratio as:

$N=\frac{k}{C}$

Now given N = 480 and C = 4.90, we first find k:

$N=\frac{k}{C}\\480=\frac{k}{4.90}\\k=4.90*480\\k=2352$

Now, as second step, we need this time to find N, when

C = 5.40

Note, we know know k = 2352, so we find N:

$N=\frac{k}{C}\\N=\frac{2352}{5.40}\\N=435.55$

Rounding to next whole number, we have 436 items
