Question

Andrew is practicing for a tennis tournamnet and needs more tennis balls.He bought 10 cans of tennis balls online and received a 25% discount . The shipping cost was $5.99.Let x representthe cost of each can .

Answer 1

The cost of each tennis ball can = $7.99

Explanation:

Here, the number of tennis ball cans purchased =10

The overall discount = 25%

The reduced price of each ball can = $5.99

⇒ The reduced price of 10 cans = 10 x ( reduced price of each ball can)

= 10 x ($5.99) = $59.90

Now, let us assume the cost of each ball can = x

So, the cost of 10 ball can = 10 times x = 10 x

Also, The reduced amount = Cost of 10 cans -Reduced maount of 10 cans

= 10 x - $59.90

⇒ 25% of 10 x = 10 x - $59.90

⇒
`(25)/(100) * (10x) = (10x - 59.9)\\ \implies 2.5 x = 10x - 59.99\\7.5 x = 59.9\\\implies x= 59.9/7.5 =  7.986`

or, x = 7.99

Hence, the cost of each tennis ball can = $7.99
