Answer:
$192.50
Step-by-step explanation:
12*38.50=462
7*38.50=269.5
462-269.50=192.50
10 cents, cause the {ball +$1.00=$1.10} subtract $1 from both sides the ball=$0.10
C. No, this is not a valid inference because she asked only 35 families
Answer:
y = 8x-37
Step-by-step explanation:
y=mx+c
We know the slope m
y=8x+c
We know a point on the line (5,3). Substitute this in for x and y
3 = 8(5) +c
3 = 40+c
3-40 = 40+c-40
-37 =c
y = 8x-37
I=√-1 and all the steps are there
