Maya,

You need to combine like terms. Remember like terms are terms that have the same variable raised to the same power. So in the example you provided, 10d +8s+20 + 5d + 6s + 10, combine the d's together, the s's together, and the constants together.

15d + 14s + 30

18) Martha’s cell phone costs $21.95 per month and $0.20 per text message (t), sent or received. The total monthly cost of Martha’s cell phone service is represented by the expression: 21.95 + 0.20t:
What would be the monthly cost to Martha if she were to send or receive 30 texts in one month?

We will use the expression 21.95 + 0.20t, where t = number of text messages

Since we are sending 30 text messages, let t = 30
21.95 + 0.20t
21.95 + 0.20*30 (follow the correct order of operations)
21.95 + 6
$27.95
