Answer:
$55
Step-by-step explanation:
Start with $245.
Calculate to total money the commuter needs to buys 20 weeks of tickets.
Multiply the number of weeks by the price per week.
20 X $15 = $300
He will need $300 for 20 weeks of tickets.
Subtract what he has from the amount he needs.
$300 - $245 = $55
Therefore the commuter will need to add $55 to the account to afford tickets for 20 weeks.
Answer:
I think the relationship is proportional.
Step-by-step explanation:
X + 1/4x + 1/5x = 58
20/20x + 5/20x + 4/20x = 58
29/20x = 58
x = 58 * 20/29
x = 1160/29 = 40 <== the original number
