Yes, she will because 
E.X.:
<span>Divide the sales tax percentage by 100 (or simply move the decimal point two places to the left) to get the decimal equivalent of the rate. So if the tax rate was 7.375%, the decimal equivalent would be .07375.<span>Multiply the taxable price by the decimal equivalent of the rate. For example, if the taxable price was $50.00 and the rate was 7.375%, then the sales taxes would be $3.69 ($50 x .07375 = 3.6875 = $3.69 when rounded to the nearest cent). Hopes this helps if not I can explain it better.</span></span>

Prove the following limit. lim x → 5 3x − 8 = 7 SOLUTION 1. Preliminary analysis of the problem (guessing a value for δ). Let ε
Temka [501]

\displaystyle\lim_{x\to5}3x-8=7

means to say that for any given \varepsilon>0, we can find \delta such that anytime |x-5| (i.e. the whenever x is "close enough" to 5), we can guarantee that |(3x-8)-7| (i.e. the value of 3x-8 is "close enough" to the limit value).

What we want to end up with is

|(3x-8)-7|=|3x-15|=3|x-5|

Dividing both sides by 3 gives

|x-5|

which suggests \delta=\dfrac\varepsilon3 is a sufficient threshold.

The proof itself is essentially the reverse of this analysis: Let \varepsilon>0 be given. Then if

|x-5|

and so the limit is 7. QED
