Solution
Let’s calculate the total cost of the items at each store:
• Noether’s Nook: 59 + 15 + 82 + 16 = $172
• Gauss Garb: 42 + 27 + 76 + 19 = $164
• Hypatia’s Hidden Gems: 51 + 23 + 94 + 14 = $182
We notice that the least amount they would have to pay is $164. Therefore, if they want to pay the least amount of money, then the gift card should be
purchased from Gauss Garb.

Skyla wants to buy a new outfit. She wants new jeans, a t-shirt, a coat, and a hat. She searches the store flyers and finds the exact same clothing options at three different stores.

• Noether’s Nook has the jeans for $59, the t-shirt on sale for $15, the coat for $82, and the hat for $16.

• Gauss Garb has the exact same jeans for $42, the t-shirt for $27, the coat for $76, and the hat for $19.

• Hypatia’s Hidden Gems has the jeans for $51, the t-shirt for $23, the coat for $94, and the hat on sale for $14.

Skyla’s grandparents want to send her a store gift card for her birthday to cover the exact cost of her outfit. Which store’s gift card would you recommend for Skyla’s grandparents to purchase
