Kurt and four friends are
eating in the food court at South CenterMall. They will divide the bill equallyamong the five of them. Two friendsorder hamburgers and two order pizza.All of them order soda. Kevin has only $3.75 with him. What can Kurt order to so that each will pay only $3.75?

$2.50 Hot dog
$1.75 Pizza
$3.25 Hambergure
$1.25 Soda

Kurt can order a hot dog because you know that if they each pay $3.75 the total can be 5*3.75= $18.75 at max and they already bought two hamburgers, so 2*3.25= $6.50, two pizzas, so 2*1.75=$3.50, and five sodas, so 5*1.25=$6.25. Of their $18.75 they have spent 6.50+3.50+6.25=$16.25, meaning that Kurt is left with the $2.50 to buy a hot dog.

2.50 x 1 = 2.50
1.75 x 2 = 3.50
3.25 x 2 = 6.50
1.25 x 5 = 6.25
= 18.75/5

Kurt will have to order a hot dog.
AHHH THANKS BRIANNA
