Question

Lina made 9 flower necklaces. Each necklace had 16 carnations and 10 hibiscus flowers. Which equation could be used to calculate the total number of flowers used for the flower necklaces? 9 × 16 × 10 = f (9 + 16) × (9 + 10) = f 9 × (16 × 10) = f (9 × 16) + (9 × 10) = f

Answer 1

(9 × 16) + (9 × 10) = f

Explanation:

Lina made 9 flower necklaces.

We are told that :

Each necklace had 16 carnations and 10 hibiscus flowers.

Hence,

1 flower neck lace = 16 carnations + 10 hibiscus flowers

The total number of flowers used to make 9 flower necklaces is :

f = 9( 16 + 10)

f = (9 × 16) + (9 + 10)

f = 144 + 90

f = 234 flowers

Therefore, equation could be used to calculate the total number of flowers used for the flower necklaces is:

(9 × 16) + (9 × 10) = f
