Answer: It is worth it.

Step-by-step explanation:

If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.

If they send 201 - 300, they get charged 6 cents per month.

If you have sent 200 texts, your charge for the month will therefore be:

= 200 * 8

= $16.00

If you send the 201th text, you will be charged 6 cents per text. Total charge would be:

= 201 * 6

= $12.06

<em>If you send 1 more text, it will be worth it because you will save:</em>

<em>= 16 - 12.06</em>

<em>= $3.94</em>

Angie is wrapping a present for her best friend. The box is 16 inches long, 12 inches wide, and 3 inches high. How many square i
rjkz [21]
I'm assuming the box is a rectangular prism:
They're asking for the surface area so the answer should be 48*2 + 192*2 + 36*2 since it has 6 faces so S.A. = 552 square in.

Fifteen more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by
lapo4ka [179]
2x-15=3(x-15) 
2x-15=3x-45
2x+30=3x
30=x

Let's check this work!

2(30)-15=3(30-15)
60-15=3(15)
45=45

She worked 45 hours each week

 *the reason it is 2x-15 and not 15+2x is because "more than" is considered a "turn around word" meaning it is the opposite
