Answer:
The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.

Answer:
D) 1/2
Step-by-step explanation:
<u>Dilation</u> : a type of transformation that makes the figure larger or smaller.
<u>Scale factor</u> : number or the conversion factor which is used to change the size of a figure without changing its shape.
Scale factor = dimensions of the new shape ÷ dimensions of the original shape
Given:
- Length of new figure P'Q' = 3 units
- Length of original figure PQ = 6 units
Therefore, scale factor = 3 ÷ 6 = 1/2
