Answer:
Step-by-step explanation:
Given the following rates;
5 games for $15, 6 games for $17.55, 7 games for $20.10, and 8 games for $22.65
Let a be the first term = $15
d = common difference = $17.55 - $15
d = $2.55
10 games will be the 6th term given that 5 games is the first term
Using the nth term of an A.P
Tn = a + (n - 1)d
T6 = 15 + (6 - 1)2.55
T6 = 15 + 12.75
T6 = $27.75
if this pattern continues, 10 games in a week will cost $27.75
