A student bought a sandwich for 80 cents, milk for 20 cents, and pie for 30 cents. How much did the meal cost?
A $1.00
B
$1.20
C$1.30
D $1.40
E $1.60

The correct answer is C. The meal costed $1.30.

Step-by-step explanation:

Since the student bought his sandwich for 80 cents, his milk for 20 cents and his cake for 30 cents, to determine the total amount to pay we must add these values. Thus 80 + 20 + 30 gives a total of 130 cents. In this regard, the American monetary system establishes that 100 cents are equal to one dollar, with which the 130 cents would become 1 dollar with 30 cents, that is, $ 1.30.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
