A groundskeeper must buy bags of fertilizer. Each bag treats $10000$ square feet of ground and costs $\$27$. The groundskeeper can buy only whole bags of fertilizer. How much will it cost to buy the least number of bags necessary to treat $6000$ square yards of ground

Respuesta :

Answer:

$162

Explanation:

As we know that

1 square feet = 0.1 square yard

which means

10,000 square feet = 0.1 × 10,000

                                = 1,000 square yards

And, the given cost is $27

So, the cost for 6,000 square yards would be

= (6,000 square yards × $27) ÷ (1,000 square yard)

= ($162,000) ÷ (1,000 square yard)

= $162

We applied the unitary method for above calculation.
