Answer:
2 cats were cared for
Step-by-step explanation:
c= cats
d=dogs
c+d =7
1.5c+3.5d=20.50
c+d =7
solve for d
d = 7-c
substitute into 1.5c+3.5d=20.50
1.5 c + 3.5 (7-c) = 20.50
distribute
1.5c +24.5 -3.5 c = 20.5
combine like terms
24.5 -2c =20.5
subtract 24.5 from each side
-2c = -4
divide by -2
c =2
They ate 13 hot dogs in 2 minutes, so divide 13 by 2 to find out how many hot dogs he ate in 1 minute:
13 / 2 = 6.5 hot dogs per minute.
Now divide total hot dogs eaten by 6.5 to get the total time:
91 / 6.5 = 14 total minutes.
