Seems to me like the question is: What are the two numbers ?
They have to multiply to 2,800 .
It's fairly easy to find two numbers that do that, BUT ...
they're not supposed to be multiples of 10 .
1 x 2,800 = 2,800 . . . . . No good. 2,800 is a multiple of 10 .
2 x 1,400 = 2,800 . . . . . No good. 1,400 is a multiple of 10 .
4 x 700 = 2,800 . . . . . No good. 700 is a multiple of 10 .
5 x 560 = 2,800 . . . . . No good. 560 is a multiple of 10 .
7 x 400 = 2,800 . . . . . No good. 400 is a multiple of 10 .
8 x 350 = 2,800 . . . . . No good. 350 is a multiple of 10 .
10 x 280 = 2,800 . . . . . No good. 280 is a multiple of 10 .
14 x 200 = 2,800 . . . . . No good. 200 is a multiple of 10 .
16 x 175 = 2,800 . . . . . Finally ! Neither one is a multiple of 10 .

because radius is half of diameter and then you would use this equation to solve
Answer:
577.81
Step-by-step explanation:
A = P(1 + (r/n))^n * t
A = 500 ( 1 + .075)^2
A = $577.81
X = 1.5 times (150-x)
x = 225 -1.5x
2.5 x = 225
x= 90
The more expensive book was $90
Check your answer:
x = 1.5 times (150-x)
90 = 1.5 times (150-90)
90 = 1.5 x60
90=90
