Answer:
So, after 6 months, they both have the same number of coins.
Step-by-step explanation:
Jack has 56 coins
Jill has 80 coins
Jack collect 12 coins per month
Jill collect 8 coins per month
Let after m months, they both have the same coin.
56 + 12 m = 80 + 8 m
12 m - 8 m = 80 - 56
4 m = 24
m = 6
So, after 6 months, they both have the same number of coins.
Answer:
0 and 2
Step-by-step explanation:
Let the two consecutive integers be 2x and 2x+2
We are given that twice the larger integer is four more than half of the smaller integer
So, Two consecutive integers are 2(0)=0 and 2(0)+2=2
Hence the two consecutive integers are 0 and 2
Answer:
P = 25 + (15)n
Total amount paid by David = $100
Step-by-step explanation:
Given:
Fixed cost of renting chain saw = $25
Variable cost of renting chain saw = $15 per hour
Time taken = 5 hour
Find;
Total amount paid by David
Computation:
Assume;
Total amount paid by David = P
Time taken = n
So,
P = 25 + (15)n
P = 25 + (15)(5)
P = 25 + 75
P = 100
Total amount paid by David = $100
