Answer:
The mass of sunflower seeds he bought = 600g.
Step-by-step explanation:
Given:
selling price of melon seeds for 100g= $3.20
selling price of sunflower seeds for 100g = $2.80
Total amount spent by Keddy on two seeds = $48.80
Keddy bought 400g more melon seeds than sunflower seeds.
To find:
The mass of sunflower seeds he bought.
Solution:
Cost of 100 g melon seed= $3.20
Cost of 400g melon seeds =4×3.20 = $12.80
Total amount Keddy spent = $48.80
Amount spent more for melon seeds = $12.80
Amount spent for both seeds excluding 400g melon seeds= $48.80- $12.80 = $36.00
here $36.00 is spent for both seeds and is of equal quantity.
Let us consider for 600g .
cost of 600g melon seeds = 6×3.20 = $19.20 and
cost of 600g sunflower seeds = 6×2.80 = $16.80
cost of 600g melon and 600g sunflower seeds = $19.20+ $16.80
= $36.00
Therefore the mass of sunflower seeds he bought = 600g.
