He spent 0.25 dollars or 25 cents
Answer:
Good for you
Step-by-step explanation:
N=7 r=2
So 7x2=14
7x3=21
7x4=28
So 3
negative x negative = positive
negative x positive = negative
positive x positive = positive
so answers are
1 = positive
2 = positive
3 = negative
4 = negative
5 = positive
The first two numbers of each result are the product of the two numbers
E.g. 8x2= 16- which are the first 2 numbers of 16106
The second set of numbers are the sum of the two numbers
E.g. 8+2=10- which are the next two numbers of 16106
The last set of numbers are the difference between the two numbers
E.g. 8-2= 6- which is the last number in 16106
Just apply this system to all the equations, but take care in noticing whether 1 or 2 digits are involved. Hope this helps!
