Question

A daycare charges a base fee of
\[3\] dollars plus
\[0.50\] dollars per minute for late (after closing time) pick-ups. Albin had to pay
\[10.50\] dollars for a late pick-up.
Albin uses the equation,
\[10.50=0.50a+3\] to represent the situation.
What does the variable
\[a\] represent in the equation?
Choose 1 answer:
A
Number of minutes of Albin's late pick-up
B
The part of the cost that depends on the number of minutes late
C
The number of dollars per minute late

Answer 1

A. Number of minutes of Albin's late pick-up

Reason: 0.50 is dollars per minute, so 0.50·a is the extra dollars for a minutes late; adding the $3 base gives the total $10.50.
