In 90 days, Jerome saved $31.50. What was his average daily savings?
A $1.05
B $3.70
C $0.15
D $0.04
E $0.35
F none of these
The correct answer and explanation is:
The correct answer is A: $1.05.
To determine Jerome’s average daily savings, you need to divide his total savings by the number of days he saved.
Jerome saved $31.50 over 90 days. To find his daily savings, use the formula: Average Daily Savings=Total SavingsNumber of Days\text{Average Daily Savings} = \frac{\text{Total Savings}}{\text{Number of Days}}
Substitute the values: Average Daily Savings=31.5090=0.35\text{Average Daily Savings} = \frac{31.50}{90} = 0.35
So, Jerome saved $0.35 per day on average. However, the answer choice that corresponds to $0.35 is not listed, leading to the correct answer being “none of these”.
