Answer:
Travis can buy a new bed for Rusty and 5 packages of dog treats for a total cost of $75 with a shipping fee of $15.
Explanation:
Let x be the number of packages of dog treats Travis wants to buy.
The cost of the dog bed is $45.
The cost of the dog treats is $6 per package.
The shipping fee is $15 for orders less than $90.
To find out how many packages of dog treats Travis can buy without exceeding the $15 shipping fee, we can set up an inequality:
6x + 45 + 15 ≤ 90
Simplifying and solving for x, we get:
6x ≤ 30
x ≤ 5
Therefore, Travis can buy up to 5 packages of dog treats without exceeding the $15 shipping fee. If he buys 5 packages of dog treats, the total cost of his order will be:
Total cost = Cost of dog bed + Cost of 5 packages of dog treats + Shipping fee
Total cost = $45 + ($6 * 5) + $15
Total cost = $75
So, Travis can buy a new bed for Rusty and 5 packages of dog treats for a total cost of $75 with a shipping fee of $15.
