Answer:
1.3
Step-by-step explanation:
Slope = 1.3
(7x - 4x) + (5 - 16)
3x - 11
In these problems, it is always a good idea to find the total population. In this case, it would be the total number of people who went on the field trip.
28+18+4=50
There are 50 people total.
To find each fraction, just put the number of students/parents/teachers over 50 and simplify.
Students
28/50=14/25
Parents
18/50=9/25
Teachers
4/50=2/25

The rate of interest is 25%
<u>Explanation:</u>
Given:
Principal, P = $2,000
Amount, A = $2500
Time, t = 1 year
Rate of Interest, r = ?
We know:
On substituting the value we get:
Therefore, the rate of interest is 25%
Hey there! Hope I can help!
<span><span>P is the principal amount, $550.00.
</span><span>R is the interest rate, 3% per year, or in decimal form, 3/100 = 0.03.
</span><span>T is the time involved, 10 year(s) time period.
</span><span>So, t is the 10 year time period.
</span></span><span>To find the simple interest, we multiply 550 × 0.03 × 10 to get $165.00
</span>
<span>Then the interest is added onto the principal to figure the new amount after 10 years. </span>
<span>550.00 + 165.00 = 715.00 > $715.00 after 10 years.</span><span>
Hope this helps!
