Hello from MrBillDoesMath!
Answer:
Discussion:
I stared at the numbers 19, 29, 39, 49, 59, 69,... for a second and noticed that adding 10 to any number gives the next number to the right. For example,
19 + 10 = 29
29 + 10 = 39
39 + 10 = 49
etc.....
A recursive formula would be:
a(0) = 19
a(n+1) = a(n) + 10 if n >= 0

Answer:
Step-by-step explanation:
profit, p = 6 × $50 = $300
losses, l = 120 + 30 + 200 = $350
overall = p - l = -$50
loss of $50

There are 2 answers: choice C, choice D</h3>
====================================================
Explanation:
32% = 32/100 = 0.32
32% of 400 = 0.32*400 = 400(0.32), which adds onto the original 400 to get 400+400(0.32). This is why choice D is one of the answers.
We can factor out the GCF 400 to go from 400+400(0.32) to 400(1+0.32) which then simplifies to 400(1.32) or just 400*1.32. This shows choice C is the other answer. Using a calculator,
400+400(0.32) = 400 + 128 = 528
400*1.32 = 528
meaning that 400+400(0.32) = 400*1.32
The other answer choices result in other values, showing that they aren't equivalent to 528.
