Question 945055: MC Taco sold 46 orders for tacos last Thursday for a total of $132. Regular taco orders sell for $2.50 and large orders sell for $3.50 How many orders of each size were sold that Thursday.
Please help, I've been out of school for many yrs. I'm trying relearn what I've forgotten, I graduated high school in 1972 with some college many yrs ago, so please me put this into a formula, I am rusty. Thanks so very Much.

***
let x=number of regular orders sold
46-x=number of large orders sold
..
2.50*number of regular orders sold+3.50*number of large orders sold=$132
2.50x+3.50(46-x)=132
2.50x+161-3.50x=132
1.00x=29
x=29
46-x=17
number of regular orders sold=29
number of large orders sold=17
