Answer:
0.01707779886
Step-by-step explanation:
Just do 27/1581
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
Answer:
9
Step-by-step explanation:
The constant is the plain number that doesn't have a letter attached.
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.
You can see that the price of the first pack is less than twice the price of the second whereas you get lot more than twice much more pencils for it (30>24) so the first deal is clearly way better.
