Answer:
$505
Step-by-step explanation:
Assuming the listed expenses comprise all of Amy's income (x), we have ...
(1/4)x +(1/12)x +(1/6)x + 590 +925 = x
1515 = 1/2x . . . . . . subtract 1/2x
We note that 1/6x is for food. That amount is 1/3 of 1/2x, so the amount spent on food is ...
(1/6)x = (1/3)(1/2x) = (1/3)(1515) = 505
Amy plans to spend $505 on food.
Answer:
Always true
Step-by-step explanation:
If you can't express the number as a ratio of integers, multiplying or dividing it by integers will not make it so you can.
If π is irrational, 2π is also irrational.
It is <em>always true</em> that the product of a rational and an irrational number is irrational.
