Let x be the number of 30 days.
(a) 65 - 2.5x = 55 - 2x
(b) 65 - 2.5x = 55 - 2x
65 - 55 = 2.5x - 2x
0.5x = 10
x = 20
Therefore, each card will result in the value of $15 when they have equal value.
The true statements about Marcus graph are:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
<h3>How to determine the true statement</h3>
From the complete question, we have the following parameters:
<u>Phone service 1</u>
- Initial cost: $40
- Rate: $8.50 per service
<u>Phone service 2</u>
- Initial cost: $30
- Rate: $10.50 per service
By comparing the above parameters:

You can then write really big numbers without running out of space
for example instead of 2300000000000000000000000000
you can just write 2.3 x 10^27
I got 5:3 and 8:15 Try at least the 5:3 because I got right
