There were 11 birds at the shelter on Wednesday.
Step-by-step explanation:
Cost of care for one bird = $4.00
Cost of care for one cat = $8.00
Total spent = $148.00
Total birds = 24
Let,
Number of birds = x
Number of cats = y
According to given statement;
x+y=24 Eqn 1
4x+8y=148 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 3 from Eqn 2;
Dividing both sides by 4
Putting y=13 in Eqn 1
There were 11 birds at the shelter on Wednesday.

Make a box putt the 70% at the top on the ouside then sub 100%-70% the box should have 4 squares so then on the bottom of the box on the outside. it should be 30% then in the top left corner put 28 and under it 46 then do
46/28 × 70% over 1 see if that helps
Answer:
20 helmets were sold ($500)
4 bikes were sold ($2000)
Step-by-step explanation:
Bikes: $500 each, helmets: $25 each
Ratio of helmets to bikes 5:1, or $125:$500, which totals to $625
$2500 ÷ $625 = 4
5:1 x 4 = 20:4
$125:$500 x 4 = $500:$2000
