This is an urgent question and I do not know what to do! This homework is due in 17 minutes!!! Sara wants to buy some billboards. The company she is buying the billboards from sells: billboards with 4 lines for $20 and billboards with 6 lines for $30. If Sara buys 7 billboards for 140, what type of billboard did she buy? Show the steps

Sara bought billboards with 4 lines for $20 (the quantity is 7)

We have to take the total cost (t) and divide that buy the 6 lines billboards and the 4 line billboards.

So, let's divide $140 by 20 and 30 (the cost for each type of billboard).

$140 ÷ 30 = 4.6

This can not be the answer because Sara bought 7 billboards, not 4.6

$140 ÷ 20 = 7

So, the answer is Sara bought billboards with 4 lines for $20.

Hope this helps you!

billboards with 4 lines for $20 (7 count)

140 divided by 30 is not 20.

140 divided by 20 is 7.

The answer to the question = 7
