We can make a proportion:
let x = cost per 1 candy bar

x is already explained
350 is $350
1 is 1 candy bar
1000 is 1000 candy bars
then, we cross multiply to get:
350=1000x
divide both sides by 1000 to get
x = 0.35
so each candy bar costs $0.35, or 35¢ (the unit cost per candy bar is $0.35, or 35¢)
We can combine only the numerals -7 and -12: r + s - 19.
Next time, please share the answer choices. Thank you.

Technically she would save $14 if we rounded up. But most stores will round down in order to save more money.
Terms are 3x, 5, 2x, and x.
Like terms are 3x and 2x.
Coefficients are 3 and 2.
Constant is 5.
lmk if anything is incorrect!!
