Answer:
y = 2x
Step-by-step explanation:
Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:
1 present wrapped -> 2 centimeters of tape
x presents wrapped -> y centimeters of tape
1/x = 2/y
x = y/2 -> y = 2x
From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.
