Simply divide 80 by 40%, or .4
80/.4= 200 check by multiplying 200 by .4 or 40%
200 x .4 = 80
Answer:
c) 50 ≤ y ≤ 170
Step-by-step explanation:
range is the set of y values and y = the cost
8>4 because eight is more than four and 4>1 so the answer is simply 8>4>1
1. answer is $246.68 (rounded) because 230 x 1.0725 (multiplier) is $246.675.
2. answer is B
3. answer is A rounded because you will get (51.5962...)
4. answer is A because when divide 40 by 42.59 you get 1.06475 (but that is the multiplier) so the answer is A
5. answer is A because 12000x 1.04 is 12480 and 12480-12000=480
6.I guess the answer is D but the total he earns is $2440 but from the one car he earns $2240 +$200 (which he earns anyway)
7.answer is A $9.16
8. the answer is B
(J-)Hope this helps
Answer
