B) Hosta: $9, Geranium: $6
C) Hosta: $7, Geranium: $8
D) Hosta: $10, Geranium: $5

Answer :

Final answer:

The cost of one hosta is $9 and the cost of one geranium is $0.47. the correct option is A) Hosta: $9. Geranium: $0.47.

Explanation:

  1. Emily spent $94 on 10 hostas and 2 geraniums. Therefore, the cost of 10 hostas is $94. To find the cost of one hosta, we divide $94 by 10: $94 / 10 = $9.40. So, the cost of one hosta is $9.40.
  2. Jimmy spent $31 on 3 hostas and 2 geraniums. Therefore, the cost of 3 hostas is $31. To find the cost of one hosta, we divide $31 by 3: $31 / 3 = $10.33 (rounded to two decimal places). Since the cost of one hosta is the same for both Emily and Jimmy, we can take the average of their costs: ($9.40 + $10.33) / 2 = $9.87 (rounded to two decimal places). So, the cost of one hosta is approximately $9.87.
  3. To find the cost of one geranium, we can subtract the cost of one hosta from the total cost of Emily's purchase: $9.87 - $9.40 = $0.47. So, the cost of one geranium is $0.47.


Therefore, the correct option is A) Hosta: $9. Geranium: $0.47.
