the germination rate for zinnia seeds is 78%. this means that 78 out of every 100 seeds will sprout and grow. if james wants 60

Harlamova29_29 [7]

Answer: 77 seeds

Step-by-step explanation:

Given: The germination rate for zinnia seeds =78%

Let x be the total number of seeds he planted, then

The seeds germinated= 78% of x

⇒The seeds germinated= 0.78x

If James wants 60 zinnia plants for his yard, then it will give the equation

$0.78x=60\\\Rightarrow\ x=\frac{60}{0.78}\\\Rightarrow\frac{6000}{78}\\\Rightarrow\ x=76.92307\aprrox77$

Hence, he should plant 77 seeds .
