Jim runs a food cart and during a busy outdoor festival he sold $7343.75 worth of food. he sells hot dogs for $2.95 and steak sandwiches for $9.95. if he sold a total of 985 items that day, how many of each item did he sell? and show your work
Answers
$2.95 hot dogs (h)
$9.95 steak sandwiches (s)
985 items sold
so what you want to do is set up two equations
h+s=985
2.95h+9.95s=7343.75
solve one of these equations for a variable
h+s=985 subtract s
h=-s+985 plug into other equation
2.95(-s+985)+9.95s=7343.75 multiply out
-2.95s+2905.75+9.95s=7343.75 combine like terms
7s+2905.75=7343.75 subtract 2905.75 from both sides
7s=4438 divide by 7
s=634 then plug this number into one of the equations preferably the simpler one
h+634=985 subtract 634 from both sides
h=351
the amount of hot dogs sold is 351 and the amount of steak sandwiches is 634
i hope this helps.

35 = - 5/9x
mutiply both sides by -9/5
35*-9/5= -5/9x*-9/5
Cross out 5 and 35, divide by 5.
35/5= 7
-5/5= -1
Cross out the 5 and 5 , divide by 5.
Cross out the 9 and 9, divide by 9.
then becomes 1*1*x= x
