PLS HELP CAN SOMEONE ANSWER B AND C 2. 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 User 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.

(a) The system of equations is:

2r + b = 8.40

3r + b = 9.35

(b) The graph is attached down

(c) By using the graph

The cost of the refill is $0.95

The cost of the egg breakfast is $6.5

Step-by-step explanation:

Let r is the amount charged for a refill and b for  the amount charged for the egg breakfast

∵ r is the amount charged for a refill

∵ b is the amount charged for the egg breakfast

∵ You ordered 2 drink refills and the egg  breakfast, for a total of $8.40

∴ 2r + b = 8.40 ⇒ (1)

∵ Your friend ordered 3 refills and the egg breakfast for $9.35

∴ 3r + b = 9.35 ⇒ (2)

(a) The system of equations is:

2r + b = 8.40

3r + b = 9.35

(b) The graph is attached down

From the graph

The red line represents equation (1)

The blue line represents equation (2)

The two lines intersected at point (0.95, 6.5)

(c) By using the graph

The cost of the refill is $0.95

The cost of the egg breakfast is $6.5

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
