Answer:
Question 9
Step-by-step explanation:
9a:
i. 23
ii. 195
iii. 2.76
9b:
i. 32, 83, 4.35
ii. 14, 11, 2.46
Number of servings = 8 1/4 ÷ 3/4
= 33/4 ÷ 3/4
= 33/4 × 4/3 = 11
= 11 servings.
Initial number of students: 220
Final number of students : 180
Multiply the initial number of students (220) by the percentage change in decimal form (divided by 100) - That expression must be equal to 180.
220 x = 180
Solve for x:
x=180/220
x= 0.818181
multiply by 100
81,81 %
100%-81,81% = 18.18%
Percent change: 18.18%
