Question

math is ahrd for me and i need this answer

Answer 1

% Increase: (End Cost - Beginning Cost)/(Beginning Cost)

In this scenario gas started at $2.78, and increased to $3.34.

Therefore the price increase can be determined by solving:

($3.34-$2.78)/($2.78)

Broken down into steps:

1) ($3.34-$2.78)=$0.56

2) $0.56/$2.78=0.201439

3) We determined that the price of gas increased by 20.14%
