The student council is having a dinner fund-raiser. the cost to rent the banquet hall for an evening is $185. the cost per plate of food is $3.50. if the tickets to the dinner banquet are $17.50 per person, how many people must attend in order for the school to earn a profit?

Given

cost to rent the banquet hall for an evening is $185. The cost per plate of food is $3.50. If the tickets to the dinner banquet are $17.50 per person

find out  people must attend in order for the school to earn a profit.

To proof

banquet hall cost =$185

cost per plate of food =$3.50

tickets to the dinner banquet =$17.50

let the number  of people attend the  dinner = x

the equation becomes

17.50x - (3.5x + 185) ≥ 0

now solving the above equation

17.50x - 3.5 x ≥ 185

14x ≥ 185

x ≥ 13.21

x ≥ 14 (approx )

To earn profit 14 people must attend the dinner.

Hence proved

(B) 1:2

Step-by-step explanation:

Looking at this, we can add to get 50, the total amount of minutes spent exercising.

Now, we can also see that Arnold spent 25 minutes lifting weights.

So he spent of his time lifting weights.

That fraction is just a ratio.

Let's simplify that fraction.

or 1:2.

So the ratio of the minutes lifting weights to the entire workout is 1:2.

Hope this helped!
