Emma and Brandon went to the Bronx Zoo. They both bought a ticket for the skyline for $20.95 and they each bought an ice cream cone for c dollars. Which expression would NOT represent the total cost that Emma and Brandon spent?

anything apart from 41.9 + 2C in dollars is not what they spent

Step-by-step explanation:

Emma and Brandon bought ticket each worth of $20.95

So they spent 2*20.95= $41.9 on ticket.

They bought an ice cream cone each wirof c dollars

Total ice cream cone worth = 2*C

= $2C

So total amount spent = 41.9 + 2C

So anything apart from 41.9 + 2C in dollars is not what they spent

21

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
