Answer:
Step-by-step explanation:
Let us assume that she makes 10 minutes of call.
Telecorp has a flat rate of 7 cents per minute. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.07 × 10 = $0.7
America's charges 25cents per call. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is $0.25
Phone busters charges 35 cents per call and 2 cents per min. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.35 + 10 × 0.02
= 0.35 + 0.2
= $0.55
The cheapest service is that of America's. Therefore, she should choose it.
Answer:
Jason sold 22/51 of the total sales and Trinity sold 29/51 of the total sales.
Step-by-step explanation:
Assuming that Trinity and Jason are the only ones selling ads, we much combine their sales to find the total sales. Then we can set up a proportion for each individual and reduce their fraction.
If Trinity sold $2030 worth of ads and Jason sold $1540 then
2030 + 1540 = 3,570
Trinity and Jason have a combined total of $3,570 is sales.
Trinity's fraction then becomes
2030 / 3570
Which can be reduced to
29 / 51
Jason's fraction of sales is then
1540 / 3570
Which reduces to
22 / 51
Answer:
see below
Step-by-step explanation:
There are some subtleties here.
<u>Drawing conclusions</u>
When conclusions are drawn based on patterns, it is called <em>inductive</em> reasoning. When those conclusions are drawn based on facts, it is called <em>deductive</em> reasoning.
<u>Theories and proofs</u>
When a pattern is observed, it gives rise to a <em>conjecture</em>. If there is a <em>counterexample</em>, then the conjecture must be declared false. If an argument can be made based on logic, then the conjecture is said to have a <em>proof</em>. A proven conjecture (statement) can then be referred to as a <em>theorem</em>.
No because 1/3(30) would be equal to 10 and 10 is not equal to 15
