Question

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.

Answer 1

`p=(200-5s)/(11)`

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

`11p+5s=200`

Solve for p

That means ----> isolate the variable p

subtract 5s both sides

`11p=200-5s`

Divide by 11 both sides

`p=(200-5s)/(11)`
