Card A:
<span>$4,350 x 0.02 = $87
</span><span>$360 - $87 = $273
Card B:
Interest $270 no rebate
so $273 - $270 = $3
Card B cost least and $3 less than card A</span>
Answer:
v=520 -10t
Step-by-step explanation:
the rate of decrease is given a variable to calculate the rate of change. v is represented by 520 - the number of minutes.
The answer is 325, 20 + 205 + 100 = 325
Your answer is E. $25.
First let under 12 = u, over 12 = o, and adults = a.
We can now write the equations:
2u + 3a + 3o = 174
4u + 2a = 122
a + o = 46
Because we know that a + o = 46, and 3a + 3o is in the first equation, we can multiply 46 by 3 to get what 3a + 3o equals. This makes 138.
Now we can substitute 138 into the first equation to get 2u + 138 = 174
2u = 36
u = 18
Now that we know what u equals, we can substitute it in to the second equation to get:
4(18) + 2a = 122
72 + 2a = 122
2a = 50
a = $25
