Rafael has $200 on a gift card. He uses it to purchase $4.50 cups of coffee before work.
So the Rate of change is ?

This is also for all my points

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

Evaluate the expression for the given value of the variable 7a - 4a for a =8
