The equation in the problem solves the speed as 48.99 miles per hour. At this speed the car takes 100 feet to stop ( also shown in the equation as they replaced d with 100).

This means any speed below 48.99 miles per hour would stop before hitting the tree.

The fastest the car can go would be 48.98 miles per hour.

Justify by replacing s in the equation with 48.98 and solve for d:

48.98 ^2 = (sqrt( 30(0.8)d)

2399.04 = 24d

D = 2399.04/24

D = 99.96 feet

This is less than 100 feet so the car will not hit the tree.

Florencia cannot spend more than $60 on clothes. She wants to buy jeans for $22 and spend the rest on shirts. Each shirt costs $
Amiraneli [1.4K]

Answer:

(8s + 22) ≤ 60

Step-by-step explanation:

Let the number of shirts Florencia bought = s

Cost of one shirt = $8

Therefore, total cost of the 's' shirts= $8s

She bought a jeans for $22 and rest amount she spent on shirts.

Total expenditure = $(8s + 22)

Since, she can not exceed her expenditure beyond $60.

So the inequality will be,

(8s + 22) ≤ 60
