Answer:
1. $64
2. 20%
3. 25%
4. $65.50
Step-by-step explanation:
1. 80 x 20% = ?
method = 80 x 0.20 = 16 = $16 80-16 = 64 = $64
2. 14 x ? % = $11.20
method = We divide 11.20/14 = 0.8 = 0.80 = 80% inverse of 80% = 20%
proof 14 x 0.20 = 2.80 so; 14 -2.80 = $11.20
3. 1000 x ? = $750
method = 1000/750 = 0.75 0.75 = 75% inverse on original price = 25%
4. $55 x 10% = ?
method = 55 x 1.10 = 65.5 = $65.50
The answer is given by the empirical rule, 68%.
Answer:
t = 20 + q in minutes
Step-by-step explanation:
Company meeting = president speech + questions + answers
President speech = 20 minutes
Questions and answers = q minutes
Total time spent = t minutes
Total time spent = President speech + Total time spent
t = 20 + q
The equation that represents the relationship between q and t is
t = 20 + q in minutes
