Answer:
15
Step-by-step explanation:
16^2-1^2=15
Its in the tens place so the unit value is 30
SI = PRT /100
1. SI = 400*5*1/100
= 2000/100
= $ 20
2. SI = 1000*8.5*3/100
= 25.5*1000/100
= $ 255
3. SI = 200*9*1/2*100
= 900/100
= $9
4. SI = 20000*12*3/100
= 200*12*3
= 7200
5. SI = 1200*4.5*6/12*100
= 4.5*6
= $27
Amount to pay = Principal + SI
= 1200+27
= $1227 ( But this answer isn't there in the options )
Step-by-step explanation:
For 2 people it uses 1 1/3 cups

So for 4 people Tomas will use
1 1/3 + 1 1/3 = 2.66 or 2 2/3 cups
