Don’t know what the price of $137.70 is paying for. Do you have any dimensions?
Answer:
The unknown value is 38.2
Step-by-step explanation:
Let z = unknown
(89/100) × z = 34
z = 34 ÷ (89/100)
= 34 × (100/89)
= 38.2 (3s.f)
Each month Wang Yong payed 170 (I got this answer by subtracting 6460 from 8500 then I got 2040 divided it by twelve and got 170)
Order of operations is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)
= (52 + 6) - (7 * 4) + 8
work inside parentheses first
= 58 - 28 + 8
work left to right now
= 30 + 8
= 38
SONYA'S MISTAKE
= (52 + 6) - (7 * 4) + 8
I think she added the 52, 6+4, multiplied 7*4 to equal 28, then added the 6+8 to equal 14
= 52 + 28 + 14 + 10
= 104
ANSWER: 38
Hope this helps! :)
