Ok so Jessica bought M pens, which cost $6.70 each.
She also bought 4 fewer pencils than pens, or (M-4) pencils, at $3.50 each.
So in total, she spent:
6.7M + 3.5(M-4)
= 6.7M + 3.5M - 14
= 10.2M -14
So she spent $(10M - 14) on pens and pencils.

Answer:
original price $75
discount $18.75
sale price $56.25
Step-by-step explanation:
I found a pair of dress pants for $75.
Since the discount is 25%, then the discount is
25% of $75 = 0.25 × $75 = $18.75
The sale price is the original price, $75, minus the discount, $18.75.
$75 - $18.75 = $56.25
