Answer:
5 packs of paper.
Step-by-step explanation:
Let x be the number of packs of paper.
We have been given that a pack of paper costs $3.75 including tax. The price of x paper packs would be .
Since Mr. Cooper has a $20 budget, so the cost of x paper pack should be lees than or equal to 20.
We can represent this information in an inequality as:
Since we can purchase whole number of paper packs, therefore, Mr. Cooper can purchase 5 packs of paper with his budget.
3.75p<=20
divide by 3.75
p < 5 1/3
he can purchase 5 packs of paper
Answer:
Step-by-step explanation:
Use FOIL: (a + b)(c + d) = ac + ad + bc + bd
and i² = -1
(6 + i)(2 + 9i) = (6)(2) + (6)(9i) + (i)(2) + (i)(9i)
= 12 + 54i + 2i + 9i²
= 12 + 54i + 2i + 9(-1)
= 12 + 54i + 2i - 9 combine like terms
= (12 - 9) + (54i + 2i)
= 3 + 56i
