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

Answer:

$p=\frac{200-5s}{11}$

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

$11p+5s=200$

Solve for p

That means ----> isolate the variable p

subtract 5s both sides

$11p=200-5s$

Divide by 11 both sides

$p=\frac{200-5s}{11}$
