Question

Yesterday I went virtual shopping on Amazon. I found that I can buy blueberry plants at a rate of 4 for $15. If I need to buy 100 plants, how much will it cost me? Please also include a tax rate of 8% in your price.

Answer 1

$405

Explanation:

For every 4 plants, it costs $15

We need 100 plants, so 100/4 = 25 sets of plants

Without tax

`25*15 = $375`

With tax included

`375 * 0.08 = 30\\375+30 = 405\\`

Hope this Helps!

Answer 2

$ 405

Explanation:

Cost of 4 plants = $ 15

Cost of 100 plants =

`=(15)/(4)*100\\\\=15*25\\`

=$ 375

Tax = 8% of 375

`=(8)/(100)*375\\\\`

= $ 30

Cost of 100 plants including tax = 375 + 30 = $ 405
