Answer:
n = -14
Step-by-step explanation:
n/2 = -7
Multiply by 2 on both sides to isolate n
n = -7 x 2
n = -14
Total ratio is 1 + 3 + 5 = 9
Share for 1 = 1/9 × 144
= 16kg
Share for 3= 3/9 × 144
= 48kg
Share for 5= 5/9 × 144
= 80kg
Proof= 80 + 48 + 16 =144
<h2>
Answer:</h2><h2>(i) Total expenses = $ 300</h2><h2>(ii) Net income(savings) = $ 0</h2>
Step-by-step explanation:
Total income earned by Sam = $ 300
(i) Expense calculation,
Clothes expense = 30 % = 30 % (300) = $ 90
Food and snacks expense = 23 % = 23 % (300) = $ 69
Cell phone expense = 14% = 14% (300) = $ 42
Transportation expense = 10% = 10% (300) = $ 30
Gym expense = 10% = $ 30
Movies expense = 8% = 8% (300) = $ 24
Apps expense = 5% = 5% (300) = $ 15
Total expenses = (90 + 69 + 42 + 30 + 30 + 24 + 15) = $ 300
(ii) Sam's net income is the profir earned after his expense.
Net income = 300 - 300 = $ 0
8+7=15
300/15=20
8 x 20 =160 Boys
7 x 20 = 140 girls
140 + 160 = 300
Hope this helps!
