Answer:
C= 25n+100
Step-by-step explanation:
Let's see what's in the graph :
- the image of 4 is 200 C(4)=200
- C(2)= 150
let m be the slope of this function :
- m=
=25
The first value in the graph is 100 wich is c(0)=100
- so the equation is : c=25n+100
Answer:
total = 96 sweets
Step-by-step explanation:
sweets shared in the ratio 4 : 5 : 7 = 4x : 5x : 7x ( x is a multiplier )
Seth got 18 more sweets than Frank , that is
7x = 4x + 18 ( subtract 4x from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
Then
total = 4x + 5x + 7x = 16x = 16 × 6 = 96 sweets
