Answer:
$6.75
Step-by-step explanation:
1: In this explanation, let's let one watermelon be w, and one orange be o.
2: From the passage, 1w + 5o = $11.
3: Also from the passage, 3w + 5o = $24.50
4: We can then use a simultaneous equation to work them out - both equations we have use 5 oranges.
3w + 5o = 24.5 (equation 1)
1w + 5o = 11 (equation 2)
5: We can now take the second equation away from the first :
3w - 1w = 2w, 5o - 5o = 0, 24.5 - 11 = 13.5
Now we know 2w = 13.5
6: If 2w = $13.50, one watermelon will be half of that, so $6.75
Hope this helps, let me know if you have any further questions :)
