Claude spends $315 to rent a car. The car he rents costs $45 per day. He has a coupon for 2 free days. Complete the equation bel
kozerog [31]

He rents for d days, but two days are free, so he pays for only d - 2 days.

The rental fee is $45 per day, so for d - 2 days, he pays 45(d - 2). The total he pays is $315, so the equation is

<u>45</u>(<u>d</u> - <u>2</u>) = <u>315</u>

Now we solve the equation to find d, the number of days.

45(d - 2) = 315

45d - 90 = 315

45d = 405

d = 9

The number of days is 9.

It will be 6 cups of flour because 6 x 5 = 30
1 x 30 = 30. 1 x 24 = 24
2 x 15 = 30 2 x 12 = 24.........
3 x 10 = 30. ........... and more on
5 x 6 = 30
6 x 5 = 30
I got 6 cups by finding the greatest common factors in 30 and 24
