Y = 7.5*200 +500
y = 1500 +500
y = 2000

<h2>
Explanation</h2>
Distributive property states that we can multiply each term outside the parenthesis with the term present inside the parenthesis. It involves multiplication and addition or multiplication and subtraction. In mathematics, distributives property is frequently used.
Some examples of distributive property are:
3 (1 + 3) = 3. 1 + 3. 3
4 (2 – 1) = 4.2 – 4.1
Simple Interest , I = PRT/100
Where P = Principal, R = Rate, T = Time in years
Time, T = (100*I)/(P*R)
T = 100* 84 / (600 * 7) Use your calculator
T = 2
Time is 2 years.
1.
180-146 = 34
2.
(5y +3) + (4y +8) + 34= 180
9y +45 = 180
9y = 135
y = 15
Answer: 15
