Polly has a very rain number of dollar bills in her purse and no change. she spends half the money on a scarf and gives $1dollar to a homeless person outside the store. she spends half the remaining dollars for lunch and tips the waiter $2. she then spends $3on a smoothie. she has $1 left. how many dollars did she have begin with?

$26

Step-by-step explanation:you do the problem in reverse adding when it says spends and multiplying when it says half. she has $1 dollar left if you work in reverse you then add $3 and get $4. then add $2 and get $6 then multiply that by 2 getting $12. you then add $1 and get $13 then the last step is multiplying and you get $26. hope this helps

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
