We have that Geraldine:
1. She has nine grandchildren.
2. She sent $30 to each of them.
3. She did this for the past five holiday seasons.
How much money has she gifted to her grandchildren?
For each season, she gave them a total of:
$30 * 9 = $270
For the total of the five seasons, we need to multiply the previous result by 5. Then:
T = $270 * 5 ---> T =$1350.
Then, she has gifted her grandchildren a total of $1350 in the past 5 seasons.
