Asap! a biologist is to set up an aquarium in his laboratory. he intends to buy 11 piranhas and 5 sharks. he has a budget of £200. if p represents one piranhas and s one shark, write down an equation for the price of one piranhas in terms of the price of sharks.

Step-by-step explanation:

Let

p ---> the price of one piranhas

s ---> the price of one shark

we know that

The price of one piranhas multiplied by 11 plus the price of one shark multiplied by 5 must be equal to the budget of £200

so

The linear equation that represent this situation is

Solve for p

That means ----> isolate the variable p

subtract 5s both sides

Divide by 11 both sides

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

you probably already have the answer but anyways it's b. 15.0
