x = total amount of gumballs
let's start subtracting the balls she's giving away


and we also know that after all that has been subtracted, she's only left with 5, so we can say that

Your answer is going to be fifteen plus r
Answer:
22.36
Step-by-step explanation:
20*.86=17.2
12 *.43= 5.16
A.P. series would be: 201, 204, 207 .... 597
Here, a = 201, d = 3, l = 597
Now, l = a + (n - 1) d
597 = 201 + (n - 1)3
597 - 201 = 3n - 3
396 + 3 = 3n
n = 399/3
n = 133
In short, Your Answer would be 133
Hope this helps!
[4.6+2×(5_2)]÷2=7
4.6+2=4.8
4.8×5=240
240_2=238
238÷2=116
