Q. Ms. Garcia buys a fancy coffee drink every day for

\$ 4

. She is thinking of getting regular coffee instead because it only costs

\$ 2

.

\newline

Ms. Garcia works out that switching could save her

\$ 1,460

a year. Does that sound about right?

Calculate Daily Difference: Ms. Garcia is considering switching from a $\$4$ fancy coffee to a $\$2$ regular coffee. The difference in cost per day is $\$4 - \$2$ . $\newline$ Calculation: $\$4 - \$2 = \$2$
Calculate Annual Savings: To find out how much she would save in a year, we need to multiply the daily savings by the number of days in a year. Assuming she buys coffee every day, that would be $365$ days. $\newline$ Calculation: $\$2 \times 365$ days = $\$730$
Compare Annual Savings: Comparing the calculated annual savings of \$\(730\) with the stated savings of \$\(1\),\(460\), we can see that the numbers do not match. Ms. Garcia's calculation seems to be incorrect.
