You can write two equations in the two unknowns. Let s and e represent the numbers of Standard and Enhanced units sold, respectively. Then the problem statement tells you
.. s + e = 19 . . . . . . . . . . . . . . . Lindsay sold a total of 19 units
.. 210s +265e = 4485 . . . . . . Lindsay took in $4,485

Since you want to know s, you can use the first equation to write an expression for e in terms of s.
.. e = 19 -s
Substitute this into the second equation.
.. 210s +265(19 -s) = 4485
.. -55s + 5035 = 4485 . . . . . . eliminate parentheses
.. -55s = -550 . . . . . . . . . . . . . subtract 5035
.. s = 10 . . . . . . . . . . . . . . . . . . . divide by the coefficient of s

Lindsay sold 10 Standard models.

How many hours do they have to work before they go to the movies
lorasvet [3.4K]

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

Perimeter= 216 

2. If 2/3 pounds is needed for 1 cheese cake and you have 2 pounds its not enough so 2 minus 2/3 will give you a mixed fraction : 1 over 1/3 or  a decimal : 1.3

 Idk if they want you to divide but if they do then your answer is 1/3
