A sports sold 200 tennis racquets. Some were sold at $18 each and the rest were sold at $33 each. The total receipts fro these sales were $4,800. How many racquets did the store sell at $18 each?
Alright you know that there are two types of raquets (lets name them x and y shall we,) you also know that the total sold is 200 raquets and $4800 was made. Set up the system: 18x + 33y = 4800 ($18 and $33 being the prices, and 4800 the total) x + y = 200 (total sold) Now just solve for x, as it represents the $18 raquets. 33x+18(200-x)=4800 33x+3600-18x=4800 15x=1200 so now go ahead and tell me what 1200 divided by 15 is
im soooo confused... howd u solve for x, howd u get those equations
@samanthagreer
ok so there were 200 sold coorect and there were $4800 made correct
yes
ok so lets set it up we have 18x + 33y = 4800 meaning that some were sold for 18 and the x means how many were sold but we dont know so that is what we are finding and the same thing with 33 and y and what do you do when a varibale or a number is right next to another number with out a sign
do you multiply it
yes
but i dont see that
great job ye you would multipy it so after that we have this ($18 and $33 being the prices, and 4800 the total) x + y = 200 (total sold) Now just solve for x, as it represents the $18 raquets.
are you understanding
im just confused how would u solve for x since there are two seperate equations and two variables in both equations
ok well we are getting there but from what i have already told you do you understadn that part
yes
great so now we will putting this together ok so i have these equations 33x+18(200-x)=4800 33x+3600-18x=4800 15x=1200 now tell me from this how do we find x 15x=1200
if you dont know just tell me and ill explain
i just dont get how u got those equations
well im not sure how to explain that but how about we finish going through the problem and then you might understand
ok
my firend showed me this but idk
i think thats how im supposed to solve it
ok so now tell me what is 1200 divided by 15
can u explain that one
80
@samanthagreer
ok so since we have that then that means that x=80 sold at $33 so we know that part but we still need to find the 18 dollar ones not tell me agina what x =
80
ok so solve this 200-x=
120
120 raquets sold at $18 each
but im soooooo sorry im still confused
200-x=120 sold at $18 well that is the answer i wil put everything agian in case you want to look over is agianAlright you know that there are two types of raquets (lets name them x and y shall we,) you also know that the total sold is 200 raquets and $4800 was made.

can u explain what my friend did
im not sure that was how i have always been taght to do it sorry
its okay thanks for taking ur time to help me i really appreciate it and i will look over the work too see if i get it
ok i hope you are able to understand
please remember to close your question
