Allen traveled for 7 hours at a constant rate of 40 miles per hour. Anna traveled the same distance at a constant rate of 50 mil
TEA [102]

Here is the correct order of the step:

Identify: Anna's time is the unknown

Strategize : let x = Anna's time

Set up : 7(40) = x(50)

Solve: x = 5.6

Check: 7(40) = 5.6(50)

<h3>What is Anna's time?</h3>

The first step is to determine the distance Allen travelled:

Distance = average speed x time

40 x 7 = 280 miles  

The second step is to determine the time it took Anna to travel 280 miles.

Time = distance / average speed

280 / 50 = 5.6 hours

Jose decided on purchasing a $145,000 home. At closing he brought a check
salantis [7]

Answer: 1

Step-by-step explanation:

Given the following:

Title fee = $545

Processing fee = $1975

Appraisal = $675

Total : $(545 + 1975 + 675) = $3195

Amount of check brought = $4645

Which is in excess of the total:

$(4645 - 3195) = $1450

Cost of home = $145,000

The percentage of the excess paid with respect to the cost of home will give the number of points Jose purchased. They are used to lower the monthly cost of a mortgage.

(Excess amount / cost of home) × 100%

(1450 / 145000) × 100

0.01 × 100% = 1%

The number of points 1 percentage point.
