Answer:
x ≤ 25mph
Step-by-step explanation:
Given that :
Speed limit drops to 15 miles per hour at curve
Driver slows down by 10 miles per hour as he drives around the curve
The driver's speed before reaching the curve is :
Let speed befure curve = x
Lowest speed before curve = 15 +. 10 = 25 mph
x ≤ 25mph
We need to solve for the total amount of money that Bianca has. But we need to consider that the total amount that Roberto has is 11 times as much money as Bianca had.
Roberto's total money is $88.
We assigned "x" variable to represent the amount that Bianca has.
Such as we can right the phrase "11 times as Bianca has" into "11X".
We have the complete expression as 88 = 11X and solving for X value, we need to divide both sides by 11.
88 / 11 = 11x / 11
8 = x
The total amount that Bianca has is $8.
