Step 1
Given:
Rate of discount on dozen cupcakes, r = 20%
Amount of discount = 4.25$
Step 2
Let the regular price of a dozen cupcakes = $x
so,
x×20100=4.25
x4.25×10020
x=$21.25

Painful bone metastases are common in advanced prostate cancer. Physicians often order treatment with strontium-89 (89Sr), a radionuclide with a strong affinity for bone tissue. A patient is given a sample containing 4 mCi of 89Sr.
If 20% of the 89Sr remains in the body after 90 days, write a function of the form Q(t)=Q0ekt to model the amount Q(t) of radioactivity in the body t days after the initial dose.
b. what is the biological half-life of 89Sr under this treatment? Round to the nearest tenth of a day.

Reduce the system
(D2 + 1)[x] − 2D[y] = 2t
(2D − 1)[x] + (D − 2)[y] = 7.
to an equivalent triangular system of the form
P1(D)[y] = f1(t)
P2(D)[x] + P3(D)[y] = f2(t)
and solve.
