Answer:
(12-3)/1.5= 6
Step-by-step explanation:
You subtract $3 from $12 for the first fee and then divide $9 by $1.50 to find how many hours you can stay.
(1/15) / (1/3) = 1/x
cross multiply
1/15x = 1/3
x = 1/3 * 15
x = 15/3
x = 5 hrs
Answer:
z = 9/2
Step-by-step explanation:
1/2z = 9 1/4?
z = 9/2
Explanation:
Simplify
9 x 1/4 → 9/4
Multiply 2 to both sides to cancel out the 2
1z = 9/4
Note: 1z is just z
Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
Monday : 2 + 10*0,25 = 2+2,5 = 4,5
Sunday : Monday - 0,3*Monday = 4,5 - 0,3*4,5 = 4,5 - 1,35 = 3,15
It's cheaper for 4.5 - 3.15 = 1,35
