Final answer:
To find the percentage of the budget that has been spent, divide the amount spent by the total budget and multiply by 100. The correct answer is 27.3%.
Step-by-step explanation:
In this question, we are given a budget of $20 for the week and we have spent $5.46. To find the percentage of the budget that has been spent, we can divide the amount spent by the total budget and multiply by 100.
Percentage spent = (Amount spent / Total budget) x 100
Substituting the given values, we get:
Percentage spent = (5.46 / 20) x 100 = 27.3%
Therefore, the correct answer is C) 27.3%.
