B. 144
C. 336
D. 152
we are to use the pie chart to find the number of students enrolled in dental hygiene care.
Letting x represent the number of students enrolled in dental hygiene care, we set the proportion equation with number of students as numerator and percentage as denominator. It should be noted that the whole pie chart represents 100% of the 800 students. Then,
We solve the value of x by cross-products.
Therefore, 144 students will enroll for a dental hygiene program.

Q #3: A pharmaceutical company’s stock price was $45.32 on Monday. On Tuesday, the price went up $3.25. On Wednesday, the price decreased from Tuesday’s price by $1.73. On Thursday, the price went up $0.89 from Wednesday’s price. Which of the following was the final price on Thursday?
A. $46.84
B. $47.73
C. $45.23
D. $48.57
Answer Explanation
we need to find the price of the stock on Thursday.
First, find the price changes in each day of the week as follows:
Monday’s price was $45.32
Tuesday’s price went up by $3.25 from Monday’s price. The price was $(45.32+3.25)=$48.57
Wednesday’s price decreased by $1.73 from Tuesday’s price, and so the price of the stock was $(48.57-1.73)=$46.84
Thursday’s price increased by $0.89 from Wednesday’s price, which was $(46.84+0.89)=$47.73
Therefore, the stock price on Thursday was $47.73.
