Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%
gizmo_the_mogwai [7]

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

Susan drove to visit a friend. She drove 345
padilas [110]

Answer:

Average\ Speed = 60 mi/hr

Step-by-step explanation:

Given

Distance = 345\ miles

Time = 5\ hours\ 45\ minutes

Required

Determine the average speed

This is calculated as thus:

Average\ Speed = \frac{Distance}{Time}

Convert time to hour:

Time = 5\ hours\ 45\ minutes

Time = 5\ hours + \frac{45}{60}\ hour

Time = 5\ hours + \frac{3}{4}\ hour

Time = \frac{20 + 3}{4}\ hours

Time = \frac{23}{4}\ hours

Time = 5.75\ hours

Average\ Speed = \frac{Distance}{Time}

Average\ Speed = \frac{345}{5.75}

Average\ Speed = 60 mi/hr
