The Corrected Problem is :
2:x and 12:18 identify the value of x that makes each pair of ratios equivalent .
Solution:
If a pair of Ratios are equivalent then we can write
(f-g)(x) = 4x²-2x-12 which,evaluated at x=4, gives 64-8-12=44
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.
