Question

i need help with this math problem 

 

Answer 1

The cost for the 3 goldfish would be 3*1.90 = 5.70

The cost for the 3 angelfish would be 3*6.10 = 18.30

The cost for the 12 neon tetras would be 12*1.53 = 18.36

 

So the total cost would be given by the following equation:

3*1.90 + 3*6.10 + 12*1.53 

=5.70 + 18.30 + 18.36

=42.36
