The answer is A. Because his current plan charges 9.75+(.12*15)=$11.55 per month while the other service charges a flat rate of $11.50 per month 5 cents less so A he should switch
Well which is less?
Amir can either pay 9.75 + 0.12(15) or he can pay a flat rate of 11.50
well 9.75 + 0.12(15) = 11.55
Since 11.55 is more than 11.50, he should switch to the 11.50 plan to save himself some money
A
y = monthly fee, x = number of checks
1st account equation:
y = 0.12x + 9.75
2nd account equation:
y = 11.5
15 checks for 1st account:
y = 0.12(15) + 9.75
= $11.55
A. Yes because his monthly fees are currently greater than $11.50
A) ===> Currently he spends 9.75 + (.12)*15 = 9.75 + 1.80 = 11.55; he’d save $.05 a month by switching
