Let's assume
number of small notebooks =x
number of large notebooks =y
we are given
total number of notebooks =31
so, we get
now, we can solve for y
we have
Small notebooks cost $3.50 and large notebooks cost $5.00
she has $134 to spend
so, we get
now, we can plug y
now, we can find y
so,
number of small notebooks is 14
number of large notebooks is 17.............Answer

Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^0 = 1 . . . . for a ≠ 0

And, it is convenient to know the cubes of small integers:
1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125
6³ = 216; 7³ = 343; 8³ = 512; 9³ = 729; 10³ = 1000
__
1) p^3 × p^5 = p^-12 × p^y
Equating exponents:
3 + 5 = -12 + y
20 = y . . . . . . . . . . . add 12

2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8
__
3) 10^x = 1 = 10^0
x = 0
