What is the simple interest that is missing from the table? use the formula i = prt.

$450.00

$450.40

$45,000.40

$45,040.00

 SECOND OPTION.

Step-by-step explanation:

You have the following formula for calculate the Simple Interest:

Where "p"is the principal amount, "r" is the rate of interest per year (it must be in decimal) and "t" is the time periods.

From the table given in the exercise, you can identify that:

Then, you must substitute these values into the formula:

Finally, evaluating in order to find the value of "I", you get the following result:

B

Step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
