The restaurant bill you and your friend received was not itemized. you ordered 2 drink refills and the egg breakfast, for a total of $8.40. your friend ordered 3 refills and the egg breakfast for $9.35.

(a) write a system of equations for the situation. use r for the amount charged for a refill and b for the amount charged for the egg breakfast.
(b) graph the equations in the system.
(c) use your graph to estimate how much each item cost.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
