Q: Leila went to the supermarket to buy food for the Christmas party. She bought apples for 5€, sugar for 3€ and carrots for 17€. She paid with a 50€ bill. How much money does the saleswoman return to her?
A: To find out how much the saleswoman should give her back, we have to find out first how much she spent. She bought apples for 5€, sugar for 3€ and carrots for 17€, so she spent 5€ + 3€ + 17€ = 25€. She pays 50€ and the saleswoman must keep 25€, so the seller must give her back 50€ - 25€ = 25€. The answer is 25.

[Question]Lisa bought a new iPhone for $1000. She bought a phone contract that costs $200/month, a case that costs 20% of the cost of the phone, and headphones that cost half as much as the case. How much will Lisa spend on her phone in the first year?
[Answer]First find the cost of the case: $1000 * 20% = $200. Then find the cost of the headphones: $200 / 2 = $100. Then find how much the phone contract will cost over a year: $200 / month * 12 months / year = $2400. Finally, add the cost of the phone, accessories, and plan over the first year to find the total: $2400 + $100 + $200 + $1000 = $3700. The answer is 3700.
Q: Alexander draws 9 pictures for an exhibition at a gallery. 5 new galleries also want Alexander to draw for them, so he draws pictures for their exhibitions too. Each of these new galleries receives the same amount of pictures. For each picture, Alexander needs 4 pencils. For each exhibition, he needs another 2 pencils for signing his signature on the pictures. If Alexander uses 88 pencils on drawing and signing his pictures for all of the exhibitions, how many paintings are at each of the 5 new galleries?
A: Alexander has sent pictures to a total of 1 original gallery + 5 new galleries = 6 galleries. For signatures, he has used a total of 6 galleries * 2 pencils per gallery = 12 pencils. So of the pencils that he used, 88 total pencils – 12 signature pencils = 76 pencils for drawings. At the first gallery, he used 9 pictures * 4 pencils per picture = 36 pencils. So in the new galleries, he used 76 total pencils for drawings – 36 pencils at the first gallery = 40 pencils. The new galleries received a total of 40 pencils / 4 pencils per picture = 10 pictures. As the new galleries all receive equal amounts of pictures, each gallery must have 10 pictures / 5 galleries = 2 pictures per gallery. The answer is 2.
