Answer to Problem 13PPS
A sample for the list of the graphing calculator is shown in the table below:
Explanation of Solution
Given information:
The given statement is:
“With every purchase at a fast food restaurant, you receive a scratch off game card with two circles. You choose one circle to scratch. One reveals a prize and the other reveals “Sorry, Try Again.” The chance that the prize on the card is cash is 5% , a sandwich is 20% , a drink is 50% , and fries is 25% .Determine how many game cards you must scratch to win the cash.”
A sample for the list of the graphing calculator is shown in the table below:
c.
To multiply the values of L1 and L2 in L3 and state what value represent that a cash prize is won.
c.

Answer to Problem 13PPS
If the value of L3 results in 1 then, it means that a cash prize is won.
Explanation of Solution
Given information:
The given statement is:
“With every purchase at a fast food restaurant, you receive a scratch off game card with two circles. You choose one circle to scratch. One reveals a prize and the other reveals “Sorry, Try Again.” The chance that the prize on the card is cash is 5% , a sandwich is 20% , a drink is 50% , and fries is 25% .Determine how many game cards you must scratch to win the cash.”
On multiplying L1 and L2 in L3, if the value of L3 results in 1 then, it means that a cash prize is won, because the value of 1 in L1 means a prize is won and a value of 1 in L2 means a cash prize.
d.
To find how many cards should be scratched to win the cash.
d.

Answer to Problem 13PPS
It will take 42 scratches to win the cash.
