Answer:
25 capsules.
Step-by-step explanation:
We are told that Joan has a prescription for 100 Theophylline capsules. Joan informs the pharmacist that she only has enough money to purchase ¼ of the prescription today.
To find the number of capsules that Joan will pay for today, we will find 1/4 of 100.


Therefore, Joan will pay for 25 capsules today.
This is the concept of density, volume and mass of different materials; To calculate for the volume of an aluminium material with density of 2.375 grams per cubic centimeter and a mass of 0.78 Kilogram we proceed as follows;
Density=mass/volume
making volume the subject we get;
volume=mass/density
thus;
mass=0.78 kg= 780 g
density=2.375 g/cm^3
Hence,
volume=780/2.375=328.421 cm^3
The triangular pyramid is made of 4 congruent triangles. They all have the same shape and size, so they have the same area. The area of one triangle is
A = b*h/2
A = 5*4.3/2
A = 10.75
So four of them lead to a total surface area of 4*10.75 = 43 square meters
--------------------------
The rectangular prism has the dimensions
L = 5
W = 5
H = 4.3
The surface area is found through the formula below
SA = 2*(L*W+L*H+W*H)
SA = 2*(5*5+5*4.3+5*4.3)
SA = 136
--------------------------
So far we found that
surface area of pyramid = 43 square meters
surface area of prism = 136 square meters
Dividing the values, we get 136/43 = 3.16279 approximately. The result is not equal to 2, so Susan's statement is not correct. The prism has more than twice the surface area of the pyramid
So he has to pay $150 a month for 1 year.
so $150×12months = $1800
