Answer:
Caleb arrived first 2 hours before Alyssa
Step-by-step explanation:
To solve the situation, find the speed per hour they were driving by dividing the distance they drove by the time it took.
Alyssa drove 105 miles in 3.5 hours or 105/3.5 = 30 miles per hour.
Caleb drove 168 miles in 4 hours or 168/4 = 42 miles per hour.
Since they both left at the same time and drove the same 210 miles to the beach, Caleb arrived first since he was driving faster.
He arrived in 210/42 = 5 hours.
Alyssa arrived in 210/30 = 7 hours.
He arrived 2 hours before her.

Answer:
It would be option two: Bill's Electric Company charges 6 dollars per hour plus a flat rate of 15 dollars for a service call. If Monica has at least 100 dollars to spend, how many hours can the service man work?
Step-by-step explanation:
6 dollars an hour means it would be 6x.
A flat rate of 15 means there would be just 15 as a number, no x's.
And the sign is less than or equal to, so she has over a hundred dollars to spend.
70% of 100 is 70 students.
Unfortunately I can not make a model for you but here's an idea:
Draw a large circle.
Next, draw a line halfway down the circle, and halfwar down draw another line to the right, this making it look like three fourths.
Then, color the larger space in one color and the other smaller space that looks like a small slice of pie in another color.
On the larger piece write "70% who got an A" and on the smaller write "30% who didn't get an A"
At the bottom you can write 70 students out of 100 got an A on the test.
