Answer:
Dane is better off buying the half liter of water for $1.21
Step-by-step explanation:
1/2 liter = $2.38
250 millilitre = $1.21
250 mm = 0.25 liter
$1.21 + $1.21 = $2.42 + $2.42 = $4.84
One liter from the 250 mm deal will equal $4.84.
So 4 liters from the 250 mm deal will equal $19.36.
$2.38 + $2.38 = $4.76
One liter from the half liter deal will equal $4.76.
So 4 liters from the half liter deal will equal $19.04.
a=3
a6=43
a+6d=43---------1
substituting a=3 in eq 1
a+6d=43
3+6d=43
6d=43-3
d=40/6
d=20/3
so first 5 no's are a, a+d, a2+d,a3+d, a4+d
a+d=3+20/d
i think u know after this
