Step-by-step explanation:
To find out what combination she can buy with her total income ($32.50) we can just multiply the price of each product by its quantity;
- If she buys 24 snickers bars and 12 cans of coke she will spend:
 (24 x $0.75) + (12 x $1.25) = $33 SHE CAN´T AFFORD TO BUY
- If she buys 24 snickers bars and 12 cans of coke she will spend:
 (22 x $0.75) + (14 x $1.25) = $34 SHE CAN´T AFFORD TO BUY
- If she buys 24 snickers bars and 12 cans of coke she will spend:
 (15 x $0.75) + (18 x $1.25) = $33.75 SHE CAN´T AFFORD TO BUY
- If she buys 24 snickers bars and 12 cans of coke she will spend:
