Answer:
I think -18
Step-by-step explanation:
The basic facts she used to help her estimate are (c) 28 + 7 and (d) 30 + 5
<h3>What are estimates?</h3>
Estimates are approximated calculations that are used in place of an actual calculation
The expression is given as:
28 + 7
When the numbers are approximated to the nearest 5, we have:
30 + 5
Hence, the basic facts she used to help her estimate are (c) 28 + 7 and (d) 30 + 5

Answer:
Step-by-step explanation
Note that
Interest is represented by I=1326
The principal is represented by P=47,600
Rate is R =4%
And Time is year
Interest is calculated using the formulae,
I =PRT/100
From the above formulae, time can be calculated as
T=100I/PR
T= 100×1326/(47600×4)
T= 132600/190400
T= 0.6964 years
To convert to days, multiply by 365(since those no of days make a year)
T= 0.6964×365=254 days
This was approximated to the nearest day
Answer is 254 days
