A party was organised for thirty people at which they could have either a hamburger or a pizza. if there were five times as many hamburgers as pizzas, calculate the number of each\

Respuesta :

b = burgers and p = pizza

b + p = 30
5p = b

5p + p = 30
6p = 30
p = 30/6
p = 5 <== 5 pizzas

b + p = 30
b + 5 = 30
b = 30 - 5
b = 25 <== 25 burgers
