Answer:
29
Step-by-step explanation:
For the two digit numbers it has to end in a zero or five and be greater than 9 and below 100.
There are 18 multiples of 5 that are 2 digit
For multiples of 7... it's easier to write it out because the total number will will less than 20.
There are 13 multiples of 7 that are 2 digits
Now you have to subtract the multiples of 7 that end in a 0 or 5
That give you 11 multiples
Add 11 and 18 to get 29

Step-by-step explanation:
The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)
here is the disffernce quotient

so
for your equation



h's cancel and you are left with 5
the differnce quotient is 5
Answer:
I think its -2,-3,0,2,5, hope its right
$0.29 * 3 = $0.87
$0.98 * 2 = $1.96
$1.39 * 1 = $1.39
0.87 + 1.96 = 2.83
2.83 + 1.39 = 4.22
10.00 - 4.22 = $5.78
she will get $5.78 back!
