Answer:
75 dollars
Step-by-step explanation:
If an item is 50 and you want to markup 50%, you must find 50% of 50 to find how much the item will go up by from 50.
So 50% of 50 means 50% times 50.
50%=.5 or 1/2
So .5(50)=25.
The item is going up by 25 dollars.
So we started at 50 dollars.
So 50+25 is going to be the new amount.
50+25=75 is the new amount.
Answer:
1. 1.5 inches per minute
2. 90 inches per hour
Step-by-step explanation:
speed = 
1. total distance covered =
+ 
= 
= 
= 4
inches
Total time taken =
+ 
= 
= 
= 3 minutes
The ants average speed = 
= 1
= 1.5
The ants speed is 1
inches per minute.
2. Since;
60 minutes = 1 hour
3 minutes = x hours
x = 
= 
= 0.05 hours
Speed = 
= 90 inches per hour
The red ants speed is 90 inches per hour.
Answer:
$80,500
55,500 + 1,500t
Step-by-step explanation:
The question is an arithmetic progression series
Where,
a= first term
d= common difference
n= number of terms
a = $70,000
d= $1,500
n= 8 years
8th term = a + (n-1) d
= 70,000 + (8-1)1500
= 70,000 + 7(1500)
= 70,000 + 10,500
= $80,500
Jocelyn salary after 8 years is $80,500
Solve for when n = t
t th term = a + (n-1)d
= 70,000 + (t - 1)1500
= 70,000 + 1,500t - 1,500
= 55,500 + 1,500t
t th term = 55,500 + 1,500t
