The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $125.25 for each ton of sugar. The second company charges $5995 to rent trucks plus an additional fee of $200.50 for each ton of sugar.
for what amount of sugar do the two companies charge the same?
in ton
Ok you have two equations here, one from the first company and one from the second company. Do you know what it is?
no i dont know the equations
Ok no problem I'll show you how I got the first equation, So the first company has a initial charge of $7500 plus $125.25 per ton of sugar. If we put it into an equation where x is number of tons in sugar, you'll get y=7500+125.25x Now, do you think you can do the second one?
yes
just replace the numbers for the second one
y=5995+200.50x
Ok great, set the two equations equal to each other to find x. To find when the amount of sugar is charged equally by the two companies. 7500+125.25x=5995+200.50x Or if you have a graphing calculator just graph it and find the intersecting point.
so solve both together?
20
Yep that's correct just make sure to include tons for your unit.
If you are unsure if its correct, just plug it back in two both equations and you should get the same answer.
there is another questin for it
what is the cost when the two companies charge the same?
Then plug 20 back into x for the two equations. You'll get the charge price.
i dont get it
7500+125.25x=5995+200.50x instead of x i put 20?
No, plug 20 in for y=7500+125.25x and y=5995+200.5x
plug 20 in for x and you'll get total price for y
i solve each?
You can if you want, or just choose one because they'll both equal the same charge price.
\[y=7500+125.25(20)=7500+2505=10005\]\[y=5995+200.5(20)=5995+4010=10005\]
yes what i got when evaluating
so that is the cost 1005?
Ok so 10005 is the amount the two companies charge, $10,005
Thank you very much
No problem, hope it helps and good luck :)
