The pulse pressure is . A) systolic pressure plus diastolic pressure B) systolic pressure minus diastolic pressure C) systolic pressure divided by diastolic pressure D) diastolic pressure plus 1/3 (systolic pressure plus diastolic pressure)

The option (B) is correct. The force generated by the heart in each contraction is the pulse pressure.  Millimeters of mercury (mmHg) is the measuring unit for the pulse pressure.

Explanation:The higher systolic pressure when subtracted from the lower diastolic pressure, gives the pulse pressure. Pulse pressure is directly and inversely proportional to the stroke volume and compliance respectively.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
