Step-by-step explanation:
8 battery =12
20 battery =?(x)
8x=240
x=240÷8
x=30
for 20 battery..it would cost 30
Answer:
eq of a line through (x1,y1) and slope m is
y-y1=m(x-x11)
y+3=3(x+4)
y+3=3x+12
y=3x+12-3
y=3x+9
$1,000
30% of $40,000 is total spendable for year
0.3*40000=12,000 yearly for rent - need to divide by 12 for monthly rent
$12,000/12 =$1000 per month maximum.
