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>
1.) Average = sum of data / number of data
Let the low temperature of Dec 17 be x, then (x + -8 + 1 + 10 - 1 + 7 + 4 + 6)/8 = 1.25
x + 19 = 1.25 x 8 = 10
x = 10 - 19 = -9
Therefore, the low temperature on 17 Dec is -9.
2.) -6+(-6)+(-6)+(-6)+[(-3)+(-3)+(-3)+(-3)+(-3)+(-3)] = -6 - 6 - 6 - 6 + [-3 -3 - 3 - 3 - 3 - 3] = -6 - 6 - 6 - 6 - 6 - 6 - 6 = (-6)(7)
The missing number is 7.
3.) (-4)(5) = (4)(-5) = -5+(-5)+(-5)+(-5)
4.) The number Loli is trying to evaluate is (-5)(3)
5.) The temperature drops by 5/10 = 0.5 degrees each day.
Let x be the day's starting temperature and y be the day's end temperature,
x - y = 0.5
6.) He looses 18/6 = 3 pounds of weight each week.
Let x be his weight at the start of the week and y be his weight at the end of the week, then
x - y = 3
7.) Jill is evaluating (-3)(4)
8.) Average = sum of data / number of data
Let the profit/los of 2008 be x, then
(-1.30 - 0.10 + 1.50 + 0.80 + 1.50 + x + 1.25 + 0.55)/8 = 0.3375
4.2 + x = 0.3375 x 8 = 2.7
x = 2.7 - 4.2 = -1.50
Therefore, the loss of 2008 is $-1.50
Answer:
2(L+w) = 190ft (Perimeter)
L + W = 95ft (190 divided by 2)
L = W + 43ft (Given)
W + 43 + W = 95ft
2W + 43 = 95ft
2W = 52ft
W = 26ft
L = 26ft + 43 = 69ft
Answer: The feild is <em>69ft by 26ft</em>

Answer:
2/5x + 28
Step-by-step explanation:
Unknown Number = x
x * 2 ÷ 5 + 7 * 4
Solve using the order of operations
2x ÷ 5 + 7 * 4
2/5x + 28
Hope this helps :)
