you are going to go to the grocery store. you have $25 to spend. there are several items on your list that you must purchase and some are “for fun” items that you can purchase if you have enough money.
your list: 2 gallons of milk for $3.50 each; 2 loaves of bread for $2.75 each; 1 pot roast for $10.45 each.
you want to also purchase some candy bars. the candy is on sale for 43 cents each. ignore sales tax and answer the following questions.
a. write an equation representing your shopping experience and use x for the number of candy bars.
b. solve the equation to determine how many candy bars can you purchase?
c. how much change would you have left?

Part a)

Part b) The maximum number of candy bars that you can purchase is 4

Part c) The change would be

Step-by-step explanation:

Part a) Write an equation representing your shopping experience and use x for the number of candy bars

Let

x -----> the number of candy bars

we know that

The inequality that represent this problem is equal to

Part b) Solve the equation to determine how many candy bars can you purchase?

Solve for x

Subtract 22.95 both sides

Divide by 0.43 both sides

The maximum number of candy bars that you can purchase is 4

Part c) How much change would you have left?

If you purchase 4 candy bars

then

therefore

expression #3 is not equivalent. the others are.

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.
