Answer:
<h2>S20=230</h2>
Step-by-step explanation:
<h2> 2,8,14,20</h2><h2>first determine whether it is arithmetic progression or geometric sequence.</h2>
<h3>Common difference (d) = second term - first term</h3>
D=T2-T1 D=T3-T2
D=8-2 D=14-8
D=6 D=6
<h3> COMMON RATIO= T2/T1</h3>
r=T2/T1 r=T3/T2
r=8/2 r=14/8
r=4 r=7/4
<h2>therefore, we can conclude that this is AP since we have the same common differences in the sequence</h2>
<h2> Sn=n/2[2a+(n-1)]. </h2><h3>where, </h3><h3>a=first term</h3><h3> n=number of terms</h3><h2> S20=20/2[2*2+(20-1)]</h2><h2> S20=10(4+19)</h2><h2> S20=10(23)</h2><h2> S20=230</h2>
Total number of snacks = 60
Total earnings = $220
Assumed all that are sold are small snacks = 60 x 3 = $180
The difference in earnings = 220 - 180 = $40
The difference in snack price = $5 - $3 = $2
Number of Large snacks = $40 ÷ 2 = 20
Number of small snacks = 60 - 20 = 40
Answer: 20 large snacks and 40 small snacks
