Answer:
For one meal each person paid 1.07 times the price of the meal (includes 7% tax).
Therefore price of each person's meal was 13.75/1.07 = $12.85
Total cost for all 5 meals was therefore $64.25--before taxes. $68.75 including the taxes.
Are you looking for a graph of the equation?
Parallel = same slope
f(x) = 4x + b
8 = 4(3) + b, b = -4
Equation: f(x) = 4x - 4
Answer:
6:15 and 8:20 are examples of additional equivalent ratios.
Step-by-step explanation:
The table is:
<u>Books (x) Cost (y)</u>
2 5
4 10
From the table, the ratio Books : Cost is 2:5 or 4:10. Equivalent ratios are obtained, using a graph, from the plot of the line that pass through these two points. In the figure attached, this line is shown. There, it can be seen that ratios 6:15 and 8:20 are equivalent to those from the table.
