U={1,2,3,4,5,6,7,8}; A={1,3,5,7} = B; C={5,8}; D={2,5,8}

A phone company charges $25.00 flat fee per month plus an additional $0.15 per text. If your bill was $34.00, approximately how

SpyIntel [72]

Answer:

60 text

Step-by-step explanation:

Let the number of text sent be $x$ .

Given:

Fee charged per month = $ 25.00

Fee charged per text = $ 0.15

Therefore, fee charge for $x$ text = $0.15\times x=0.15x$ .

Total cost for a given month = $25+0.15x$ .

Now, if for a given month, the total cost is $ 34. Then,

$25+0.15x=34\\ 0.15x=34-25\\0.15x=9\\x=\frac{9}{0.15}=60$

Therefore, the number of text sent for a monthly bill of $ 34 is 60.
