The amount earned per hour for baby sitting is the proportional
relationship between amount earned and time taken.
The friend's earnings that form the same proportion as Gina's is A. Maria
was paid $36 for 6 hours.
Reasons:
A proportional relationship between two variables, x, and y, can be
expressed as; y ∝ x
Which gives;
y = C × x
Where;
C = A constant value
The proportion formed by the numbers in the table is expressed as
follows;
Amount ($) = C × Time (h)
12 = C × 2
[tex]\therefore C = \dfrac{12 \ \$}{2 \ h} = 6 \ \$/h[/tex]
Therefore, Gina makes constant proportional amount of $6 every hour
Maria earns $36 in 6 hours, which gives;
$36 = C × 6 h
[tex]C = \dfrac{36 \ \$}{6 \ h} = 6 \ \$/h[/tex]
Therefore, Maria's earnings of a constant proportional amount of $6 per
hour forms the same proportion as Gina's.
Which gives the correct option as A. Maria was paid $36 for 6 hours.
