Nathan had $25 to spend the carnival. he spent 60% of the money on food and drinks.

$15

Step-by-step explanation:

Equation: x/25 = 60/100

Cross Multiply: 25(60) = 100x

Simplify: 1500 = 100x

Divide: 1500/100 = 15

x = 15

A) y = 20xb) y = 10x+50c) the graph is attached.d) when there are 5 people.e) with the regular price, $120; with the special, $110.explanationa) since it is $20 per person, for x people the equation would be y=20x.b) since it is $10 per person, for x people it would be 10x; we must add 50 to this total, however, so we have y=10x+50.d) set the two equations equal to one another: 20x = 10x+50subtract 10x from both sides: 20x-10x = 10x+50-10x10x = 50divide both sides by 10: 10x/10 = 50/10x = 5e) for the regular price, we have y=20(6) = 120.  for the special, we have y=10(6)+50 = 60+50 = 110.
