Question

The number of basic headphones the store can purchase if it spends a total of $10,000 on headphones and buys 110 HD headphones for $70 each.

Answer 1

The store buys 110 HD head phone for $70 each. That means they spent 110 x 70 = $7,700 on them

$10,000 - $7,700 = $2,300

The store has $2,300 dollars left to spend on basic headphones.

The answer is $2,300 ÷ cost of basic headphones

Answer 2

Total amount spent = $10,000

Cost of one HD headphones = $70

So, cost of 110 HD headphones =
`70*110=7700` dollars

Hence, amount left to purchase basic headphones =
`10000-7700=2300` dollars

So, the store can buy x headphones from $2300. Where x can be found by dividing 2300 by the cost of 1 headphones.
