To determine how much money Rick has altogether, we need to start with his initial savings, subtract the amount he spent on plane tickets, and then add the amount his friend gave him. Here are the steps:
1. Initial Savings:
Rick starts with \[tex]$680.
2. Subtract the Amount Spent on Plane Tickets:
Rick spends \$[/tex]240 on plane tickets. So, we subtract this amount from his initial savings:
[tex]\[
680 - 240
\][/tex]
3. Add the Amount Given by His Friend:
Rick's friend gives him \[tex]$50. So, we add this amount to the result from the previous step:
\[
(680 - 240) + 50
\]
Following these steps in sequence, we get:
1. Start with \$[/tex]680.
2. Subtract \[tex]$240, getting:
\[
680 - 240 = 440
\]
3. Add \$[/tex]50 to the remaining amount, getting:
[tex]\[
440 + 50 = 490
\][/tex]
Therefore, Rick has a total of \[tex]$490 after spending and receiving money.
To enter this correctly into a calculator, the sequence should follow the exact operations we followed:
\[ [ON/C][680][-][240][+][50] \]
Given the options:
1. \([ON/C][680][-][240][+][50]\)
2. \([ON/C][240][-][680][+][50]\)
3. \([ON/C][680][+][240][-][50]\)
4. \([ON/C][240][+][680][-][50]\)
The correct option is:
\[ [ON/C][680][-][240][+][50] \]
So, Rick can enter this sequence into his calculator to correctly find out that he has \$[/tex]490 altogether.
