Answer:
see the procedure
Step-by-step explanation:
we have
where
c -----> the cost in dollars
g ----> the number gallons of gas purchased
1) For g=1 gal
substitute the value of g in the equation and solve for c
The pair (1,2.95) fit the relationship
2) For g=3 gal
substitute the value of g in the equation and solve for c
The pair (3,8.85) fit the relationship
3) For g=5 gal
substitute the value of g in the equation and solve for c
The pair (5,14.75) fit the relationship
4) For c=$20.65
substitute the value of c in the equation and solve for g
The pair (7,20.65) fit the relationship

c,d,f
Step-by-step explanation:
I hope these r the answers.
$36
I think
$0.89 rounds up to $1.00
$0.75 rounds up to $1.00
$1.60 rounds up to $2.00
then multiply each by 9 for the 9 children
9
9
18
then add together
9+9+18=36
Answer:
Her second lap was <u>8%</u> better when compared to her first lap.
Step-by-step explanation:
Given:
Emily ran her first lap in 75 seconds she ran her second lap in 69 seconds.
Now, to find how much better was her second lap when compared to her first lap.
Emily ran her first lap in 75 seconds.
Emily ran her second lap in 69 seconds.
So, we get the difference in seconds:
<u><em>Thus, in her second lap she was 6 seconds better than first.</em></u>
Now, to get the percentage of her first lap better than second:
Therefore, her second lap was 8% better when compared to her first lap.
