Answer:
about 396 tacos
Step-by-step explanation:
First, figure out how many per person.
72 tacos / 50 people = about 1.44 (per person)
275 * 1.44 = about 396 tacos
396 tacos
We know that 72 tacos are sold for every 50 people.
we can organize the information we have in a table:
Tacos People
72 ⇒ 50
and we want to know how many tacos will be sold if 275 people came to the truck, if x represents the quantity of tacos:
x ⇒ 275
we can solve this problem with rule of three: multiply the cross quantities in the table (72 by 275) and the divide by the remaining amount (50)
so the quantity of tacos x is:
x=72*275/50
x=19800/50
x=396
5x 1/4
m=D x V
or M=DV
first step is to cross multiply so that M can stand alone
Answer: the first one
f(x) = 4.5x + 3/8
