Answer 1

Answer:

233 bottles

Step-by-step explanation:

In this problem, the cost of b water bottles can be found by using the equation:

$c=1.2 b +20$

where

b is the number of bottles

1.2 is the cost of each bottle

20 is the fee for the order

Here we want to know the maximum number of water bottles that Marine can order staying within a budget of $300. So we can write that the cost must be less or equal than 300$:

$1.2b+20 \leq 300$

To solve the equation, we subtract 20 from both sides first:

$1.2b+20-20\leq 300-20\\1.2b \leq 280$

Now we divide both sides by 1.2:

$\frac{1.2b}{1.2}\leq \frac{280}{1.2}\\b\leq 233.3$

So, Marine can buy at most 233 bottles.
