Answer:
Part 1) The system of equations that represent this situation is equal to
b+p=42 and 5b+2p=144
Part 2) 20 binders were sold
Step-by-step explanation:
Let
b -----> the number of binders sold
p -----> the number of pencil pouches sold
Part 1)
we know that
The system of equations that represent this situation is equal to
b+p=42
5b+2p=144
Part 2) How many binders were sold?
we have
b+p=42
p=42-b ------> equation A
5b+2p=144 -----> equation B
substitute equation A in equation B
5b+2(42-b)=144
5b+84-2b=144
3b=144-84
3b=60
b=20 binders
90% as a decimal is .9 and then as a fraction in simplest form is 9/10

Total = principal * (1 + rate / n)^(n * years)
where "n" is the number of compounding periods per year
Total = 1,500.00 * (1 + .025/4)^(4 * 4)
Total = 1,500.00 * ( <span><span><span>1.00625
