Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
Answer:
$600
Step-by-step explanation:
$450 which is 75% of the original price
75%=3/4
$450=3/4op
$450/ 3/4 =op
$450*4/3=op
$450/3=150*4=$600
500-100=400
5(400)=2000
399+10=409
2000+409+2409
5(2409)=12045
3(12045)-36135
so in total it's equal to 36135
