Answer:
"x" cantidad de personas, que será igual a
f(x) = $10x Si x < 30
f(x) = $9.5x si x ≥ 30
Si tenemos que son 29 personas entonces el costo es de:
f(x) = $10*29 = $290
Si incluye un miembro adicional
f(x) = $9.5*30 = $285
Ahorra un total de: $290 - $285 = $5

The percent of markup is 20%
Step-by-step explanation:
Selling price of the drink = $1.50
Cost of the drink last year = $1.25
Percent of markup = (selling price - cost) (100)/cost
Percent of markup = (1.50 - 1.25)(100) /1.25
= 0.25(100) /1.25
= 25/1.25
= 20%
The percent of markup is 20%
