Answer:
20
Step-by-step explanation:
First, let's find how much she spent on the expensive calculators
40 times $16400= $656,000
Now, lets find how much money she had for the cheap calculators.
$774,000- $656,000=$118000
Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.
$118000/$5900=20

Answer:
The next three terms are 10, 12.5 and 15
Step-by-step explanation:
I. As you can see 5 and 7.5 is came from 5, 5 + 2.5
So given y = 5 + 2.5( x - 1 ) when y is output, x is term
II. Perform x = 3, 4, 5
So y = 5 + 2.5( 3 - 1 )
= 5 + 5
3rd = 10
y = 5 + 2.5( 4 - 1 )
= 5 + 7.5
4th = 12.5
y = 5 + 2.5 (5 - 1)
= 5 + 10
5th = 15
