An aquarium at a pet store has 18 black neon tetra fish in it . a customer buys 12 black neon tetra fish at the same time the store clerk adds 7 more black neon tetra fish are in the aquarium now ?

18-12+7

 6 + 7

13

Write an equation.

Subtract first- the customer buys 12 black neon tetra fish which means subtraction

addition- the store clerk puts in 7 more black neon tetra fish which means your gonna add 7

18-12. Add 7. Get 13. :)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
