Answer:
Number of children = 386
Number of adults = 287
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 673 (1)
1.75x + 2y = 1249.50 (2)
From (1)
x = 673 - y
Substitute x = 673 - y into (2)
1.75x + 2y = 1249.50
1.75(673 - y) + 2y = 1249.50
1177.75 - 1.75y + 2y = 1249.50
- 1.75y + 2y = 1249.50 - 1177.75
0.25y = 71.75
y = 71.75/0.25
y = 287
Substitute y = 287 into (1)
x + y = 673
x + 287 = 673
x = 673 - 287
x = 386
Number of children = 386
Number of adults = 287

Answer:
A. b = 2/5f
Step-by-step explanation:
Andre's equation is in the form ...
b = kf
The value of k can be found by dividing by f:
b/f = k
For Priya's recipe, the values are ...
b/f = k = 3/7.5 = 2/5
Andre's equation is ...


We're given that
and
, and want to find
.
By the chain rule, we have

and


Then

(because the point
corresponds to
)
