Hi
65% of x is $ 97.50
x ⇒ 100%
97.50 ⇒ 65%
65x = 100·(97.50)
65x = 9750
x = 9750/65
x = 150
Answer: $ 150.00
<span>This is an example of a Simple interest. We have an annual rate 7% ( or r=0.07). A=18,400 + 9,016 =$27,416. The formula for calculating the Simple interest: A=P*(1+r*x), 27,416=18,400*(1+0.07x), 1+0.07x=27,416:18,400, 1+0.07x=1.49, 0.07x=1.49-1, 0.07x=0.49, x=0.49:0.07, t = 7. Answer: D) x=7 years</span>
Answer:
2
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= ( -4 - -2)/ ( 2-3)
= ( -4+2)/( 2-3)
= -2/ -1
= 2
Answer:
