Answer:

Equation: y=$3(x)+$30

Total cost $42

Step-by-step explanation:

Calculation to Find the total cost of 4 hours at the aquarium using this formula

y=mx+b

Where,

y intercept=Total cost

m=$3 per hour

b=$30 Tickets

x=4 hours

Let plug in the formula

First step is to form the equation

y=$3(x)+$30

Second step is to substitute 4 hours for m and b

y=$3(4)+$30

Hence:

y=$12+$30

y=$42

Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42
