Study Notes
Ice Cream Consumption
- Jerome consumed 3 oz. from a 16-oz ice cream pack.
- To find the percentage eaten: (3 oz / 16 oz) * 100 = 18.75%.
- Jerome ate 18.75% of the ice cream pack.
Percentage Calculation
- To determine what percent of 50 is 21: (21 / 50) * 100 = 42%.
- 21 is 42% of 50.
School Athletics Participation
- 30% of the high school population is involved in athletics.
- 15% of the athletes play football.
- To find percentage of the whole school playing football: 30% * 15% = 4.5%.
- Therefore, 4.5% of the entire school plays football.
Baseball Card Sales
- Matthew had 200 baseball cards.
- He sold 5% of the cards on Saturday: 5% of 200 = 10 cards sold.
- Remaining cards after Saturday: 200 - 10 = 190.
- He sold 10% of the remaining cards on Sunday: 10% of 190 = 19 cards sold.
- Cards left after Sunday: 190 - 19 = 171 cards remaining.
Maximizing Product of Two Numbers
- To find two numbers whose sum is 50 for largest product, use the form x and (50 - x).
- The product is maximized when x = 25 and (50 - x) = 25.
- Thus, the two numbers are both 25, giving the maximum product of 625.
