Given:
hotdog price - P10
hard - boiled egg price - P7
Sold - 22 hotdogs
Total sales must be at least P300
Hard - boiled eggs needs - ?
[tex]{}[/tex]
Let x be the number of boiled eggs Sean need to sell.
Then, by condition
22 × 10 + 7 × x ≥ 300
7x ≥ 300 - 220
7x ≥ 80
x ≥ [tex]\large\mathsf{ \frac{80}{7}}[/tex].
So, [tex]\large\mathsf{ \frac{80}{7}}[/tex] ≈ 11.43 what means if Sean sells 11 eggs which is less than 11.43), he won't have his sales. If he sells 12 eggs (which is greater than 11.43), then he will have total sales at least P300. So, he should sell 12 eggs to have a total sales at least P300
