Answer: total cost earn=$1360

adult sold =45

student sold =80

adult cost twice as student cost so we can say adult sold 45+45=90

so total sold=90+80=170  

to get the cost of 1 meal we divide 1360 by 170

1360/170=8

one student meal cost=8$

one adult meal cost=8*2=16

total students meal cost=8*80=640$

total adult meal cost=16*45=720

640+720=1360

A migrating bird flies 700 miles in 1414 hours. How many miles does it fly in 33 ​hours
Lisa [10]
In  1414 hours it covered 700 miles

In  1 hour it would have covered  (700/1414) mile

In 33 hours it will then cover :          700/1414  * 33 = 16.34

So in 33 hours it will cover ≈ 16.34 miles.

2m3 of soil containing 28% silt was mixed into 1 m3 of soil containing 13% of silt. What is the silt content mixture?
Leto [7]
Alright
so
28% of 2 m³=0.28 times 2=0.56 m³ of silt in the first mixture

13% of the 1 m³=0.13 times 1=0.13 m³ of silt in 2nd

total is 0.56 m³+0.13 m³=0.69 m³ of silt
and the total is 2m³+1m³=3m³

so
0.69/3=0.23=23%

answer is D
