Answer:
10 hours
Step-by-step explanation:
45 pages per 1 hour and 30 minutes, or 60 min +30 min =90 min
90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages
90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300

Rate of change of profit for this period is $2750 per month
<em><u>Solution:</u></em>
Given that,
Profit of $6500 in January and $17,500 in May
<em><u>To find: Rate of change</u></em>
Since,
January is the first month of the year (1) while May is the fifth month (5)
<em><u>Therefore, we get two points</u></em>
(1, 6500) and (5, 17500)
Using these points we can find the rate of change in profit for this time period
<em><u>The rate of change using the following formula:</u></em>

Here from the points,

<em><u>Therefore, rate of change is given as:</u></em>

Thus rate of change of profit for this period = $2750 per month
FIND SALE PRICE
= $230 - ($230*20%)
= $230 - $46
= $184
OR
= $230 * (100%-20%)
= $230 * 80%
= $184
*use the method you're most comfortable with or that your teachers prefer
FIND TOTAL WITH TAX
= $184 + ($184 * 11.5%)
= $184 + $21.16
= $205.16
ANSWER: The shoes with discount and taxes cost $205.16.
