Answer:
$994.5
Explanation:
At an opening of a new art gallery, the owner hired a caterer to serve light snacks. The owner created a budget for 150 people to attend the opening, with a per person food cost of $4.25.
Cost for 150 persons =
150 × $4.25 = $637.5
If the number of guests attending the opening was 56% more than expected, then how much was the final food cost?
Percentage increase = Final value - Initial value /Initial value
56% = x - 150/150
Cross Multiply
0.56 × 150 = x - 150
84 = x - 150
x = 150 + 84
x= 234 people
56% increase means 84 extra people came
Total people that came = 234 people
From the question, we know that: per person food cost of $4.25.
Hence
1 person = $4.25
234 persons =
234 × $4.25
= $994.5
Therefore, the final food cost is $994.5
