Alice likes to have wine with her dinner on Friday and Saturday night. She usually buys two bottles of wine for the weekend. She really needs to cut back on spending. She decides to buy only one bottle per week. On average a bottle of wine costs $15. How much does she save in one year?

Step-by-step explanation:

you are really struggling with such simple things ? you only need to type it into your calculator, and you have your answer in 2 seconds.

instead you are posting the question here, then you wait, if there is an answer, then you copy the answer back to your work ...

so, please tell me, what is your real problem with these questions ?

there are 52 weeks in a year.

instead of 2 bottles of $15 each she now only buys 1 bottle of $15 per week.

she saves $15 per week (one bottle instead of 2).

so, in a year she saves

15×52 = $780

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
