Answer:
45 grams
Step-by-step explanation:
1st order: 27 people
15 people:
100 g
Ginger: 20 g
Turmeric: 25 g
Coriander: 35 g
Cumin Seeds: 20 g
20+25+35+20=60+40=100
For 1 person:
Ginger: 1 1/3 g
Turmeric: 1 2/3 g
Coriander: 2 1/3 g
Cumin Seeds: 1 1/3 g
Multiply all that by 27
For 27 people:
Ginger: 36 g
Turmeric: 45 g
Coriander: 63 g
Cumin Seeds: 36 g
45 g for Turmeric
Answer:
1 pear = $0.75; 1 orange = $0.65
Step-by-step explanation:
(1) 3P + 4O = 4.85
(2) 3P + 10O = 8.75 Eqn (2) - Eqn (1)
3P + 10O – 3P – 4O = 8.75 – 4.85 Combine like terms
6O = 3.90 Divide each side by 6
O = $0.65 Substitute into Eqn (1)
3P + 4×0.65 = 4.85
3P + 2.60 = 4.85 Subtract 2.60 from each side
3P = 2.25 Divide each side by 3
P = $0.75
Oranges cost $0.65 each and pears are $0.75 each
