<u><em>Answer:</em></u>
Total number of plants = 3t - 15 = 3(t-5) tomato plants
<u><em>Explanation:</em></u>
<u>We are given that:</u>
Erin planted t tomato plants
Leo planted 5 fewer tomato plants than Erin, <u>this means that:</u>
Leo planted = t - 5 tomato plants
Fillip planted 10 fewer tomato plants than Erin, <u>this means that:</u>
Fillip planted = t - 10 tomato plants
Now, we want to find the total number of tomato plants
<u>This means that</u> we will add the number of plants planted by Erin, Leo and Fillip
<u>Therefore:</u>
Total number of plants = t + t - 5 + t - 10
Total number of plants = 3t - 15 = 3(t-5) tomato plants
Hope this helps :)
