A store charges $85 for every 5 bags of fertilizer someone buys. Table:
Fertilizer bags | 5 | _ | 15 | 20 | _ |
Cost | 85 | 170 | _ | _ | 510 |
To find the missing cost values, we can use the given information that the store charges $85 for every 5 bags of fertilizer.
For 15 bags of fertilizer, we can divide 15 by 5 to find the number of groups of 5 bags: 15 / 5 = <<15/5=3>>3 groups.
Since each group of 5 bags costs $85, the cost for 15 bags would be 3 groups * $85 per group = $255.
For 20 bags of fertilizer, we can divide 20 by 5 to find the number of groups of 5 bags: 20 / 5 = <<20/5=4>>4 groups.
Since each group of 5 bags costs $85, the cost for 20 bags would be 4 groups * $85 per group = $340.
Therefore, the missing cost values in the table are:
Fertilizer bags | 5 | 10 | 15 | 20 | 25 |
Cost | 85 | 170 | 255 | 340 | 510 |
