<p>i just don't know how to approach this problem.</p>
<p>A travel agent offers a vacation plan which costs z dollars for the first day and z/6 dollars for each additional day. How much does a vacation of y days cost, in dollars, where y>1??</p>
<p>a) yz/6
b) yz/3
c) yz+6z/6
d) yz+5z/6
e) y^2z+5yz+z^2/3</p>
<p>Also,</p>
<p>if the value of n nickels plus d dimes is c cents, what is n in terms of d and c?? I seriously cannot stand these questions with letter in them instead of numbers.</p>
<p>For the second one, we’re setting up an equation in terms of dollar value so we need convert the number of coins to the actual monetary value. A nickel is 5 cents and a dime is 10 cents, so multiply n by 5 and d by 10:</p>
<p>5n + 10d = c
5n = c - 10d
n = (c - 10d)/5</p>
<p>its D, What i did was to come up with a situation and then see which equation works.
For example
If some one uses the for plan 2 days and the cost is 6, then the cost for 2 days is 7.
The only equation that gives me 7 is D.</p>
<p>A travel agent offers a vacation plan which costs z dollars for the first day and z/6 dollars for each additional day. How much does a vacation of y days cost, in dollars, where y>1??</p>
<p>a) yz/6
b) yz/3
c) yz+6z/6
d) yz+5z/6
e) y^2z+5yz+z^2/3</p>
<p>so for at least one day it costs Cost=z
then for each additional day it costs y-1<em>z/6 because on the first day y-1=0 and the cost is z
so then Cost=z+(y-1)</em>z/6 Cost= 6z/6+yz/6-z/6 Cost=(6z-z+yz)/6 Cost=(yz+5z)/6</p>
