Answer:
It represents the total amount that Erin is going to spend at the store.
Step-by-step explanation:
The total amount that was raised for charity is £75.
<h3>What is the total amount raised?</h3>
Here is the sample space
1 2 3 4 5 6
Heads 1 4 9 16 25 36
Tails 1 8 27 64 125 216
Probability of getting a number greater than 30 = 4/12 = 1/3
1/3 x 450 = 150
Total value of people getting more than 30 : 150 x £1 = £150
Total amount paid = 50 x 450 = £225
Amount raised = £225 - 150 = £75
