Answer: billboards with 4 lines for $40 (quantity of 4)
Step-by-step explanation:
We have to take the number of dollars Sara spent (d) and divide by the number of the amount of billboards Sara bought (4). We also know Sara bought 4 billboards.
We know one billboard with 6 lines is $30
We know one billboard with 4 lines is $40
Now, we have to take the number 160 and divide by both numbers: 30 & 40
160 ÷ 6 = 26.66667
We have to remember the fact that Sara bought 4 billboards.
160 ÷ $40 = 4
The answer to the question is billboards with 4 lines for $40 with a quantity of 4.
