Easy, if he has $90 in ALL
and he spends $5 and $15
$20 in total
take, 90-20=70
So now he only has $70 left.
If each ride costs $1.50, then he's losing money.
So, y=-1.50x+70
So around the 47th ride he will have no more money.
Answer:
1 and 3/4 days are equal to 42 hours
Step-by-step explanation:
42 hours = (42 hours) (1 day / 24 hours)
42 hours = 42/24 days
Simplyfing the fraction: Dividing the numerator and denominator by 6:
42 hours = (42/6) / (24/6) days
42 hours = 7/4 days
42 hours = (4+3)/4 days
42 hours = (4/4+3/4) days
42 hours = 1 3/4 days
Step-by-step explanation:
For a geometric sequence,

1. The sequence is :
3, 13, 23, 33,...

It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625

So, the sequence is geometric as the common ratio is same. It is true.
