Answer:
-1.5x + 70
Step-by-step explanation:
Total money he takes while going to the fair = $90
Money he spends to enter the fair = $5
Money he spends on food =$15
Total he spent now is given by
Now, he spend on rides at the fair i.e. 1.50 per ride .
Let the number of rides be x
So, cost incurred on rides = 1.5x
So, the spending money can be expressed as
Now, remaining money left to him after spending on x rides too is
Let f(x) denotes the function used to determine the money he has left over after rides .
So it becomes
f(x) = 70 - 1.50x
f (x) = -1.50x +70

Answer:
t=d/s
Step-by-step explanation:
search up distance speed time triangle (like the one attached) and memorize it. When u need to use it just draw it on a piece of paper and cover ur intended target. For example, if u want to find the time formula, cover the time section and you got the time formula, D/S. It helps for beginners.
