An office manager orders one calculator or one calendar for each of the office's 80 employees. Each calculator costs $10, and each calendar costs $15. The entire order totaled $1,000.

Part A: Write the system of equations that models this scenario. (5 points)

Part B: Use substitution method or elimination method to determine the number of calculators and calendars ordered. Show all necessary steps. (5 points)

Answer 1

Did i get the last one correct? Just asking.

Answer 2

yeah

Answer 3

Okay i'll help with the equation. 80x+10+15=1,000

Answer 4

yeah ik that i nee d part b

Answer 5

Oh okay hold on.

Answer 6

srry i should have been more supicific

Answer 7

It's fine i get it.

Answer 8

alright

Answer 9

So do i just solve the equation?

Answer 10

Or what?

Answer 11

Part A:
Let c be the number of calculators ordered.
Let d be the number of calendars ordered.

The system of equations that models this scenario is:
c + d = 80 (equation 1)
10c + 15d = 1000 (equation 2)

Part B:
Using substitution method:
From equation 1, we have:
c = 80 - d

Substituting this into equation 2, we get:
10(80 - d) + 15d = 1000

Expanding and simplifying, we get:
800 - 10d + 15d = 1000
5d = 200
d = 40

Substituting d = 40 into equation 1, we get:
c + 40 = 80
c = 40

Therefore, the office manager ordered 40 calculators and 40 calendars.

Answer 12

Only needed part "B" lmao.
