F(x) = 1.25x + 12.
12 Is the cost of food, and 1.25x represents that every ride (x) is 1.25 dollars.
f(1) = 1.25(1) + 12
f(1) 13.25
If he rides one ride, then it will cost this 13.25 dollars in total
f(2) = 1.25(2) + 12
f(2) = 14.5
If he rides two rides, then it will cost 14.5 dollars in total
f(3) = 1.25(3) + 12
f(3) = 15.75
If he rides 3 rides, it will cost 15.75 dollars in total, etc. etc.
Hope this helps!!
Answer:
29.8 units
Step-by-step explanation:
2x+10 x + 3
------------ = --------------
10 4
4(2x+10) = 10(x+3)
8x + 40 = 10x + 30
2x = 10
x = 5
AE =2x+10 = 2(5) +10 = 20
answer
20 units
Let x + 15 = total penguins
15/ (x +15) = .30
15 = .30x + 4.5
.30x = 10.5
x = 35
Total penguins = 15 + 35 = 50
Double Check
15 / 50 * 100 = 30% Correct!!!
