Answer:
The missing value in the table is:
B. 15.75
Step-by-step explanation:
The table is given by:
Gallons of gas Cost in dollars
1 1.05
2 2.10
5 5.25
15 ?
20 21.00
Let x represents the Gallons of gas
and y represents the cost in dollars.
By looking at the table we observe that the relationship between x and y is linear and the equation that satisfies the equation is:
[tex]y=1.05x[/tex]
Hence, when x=15 we have:
[tex]y=1.05\times 15\\\\i.e.\\\\y=15.75[/tex]
Hence, the correct answer is:
Option: B
