Question

I'll give anyone a medal if they help me please i beg of you

Answer 1

x = number of pizza orders.
y = number of chicken orders.

There is 7 people/orders in total, so
x + y = 7

We also know the prize of each order and the total amount of money for the entire order
2.50x + 3.50y = 21.50

Now you have the follow system of equations to solve:
\[\large x + y = 7 \\ \large 2.50x + 3.50y = 21.50\]

Answer 2

Lyrae but how do you fine the answer i have to divide them all by 2.50

Answer 3

sorrry meant 3.50

Answer 4

Do you know how to solve systems of equations?

Answer 5

i think i do but this is different than the ones i did and passed

Answer 6

Normally you'd do it by substitution or by elimination, does one of those sound familiar?

Answer 7

No am sorry

Answer 8

when it comes up to these question i get very confused

Answer 9

It's okay :) Everyone's confused in the beginning when learning something new!

Here's the solution using substituition:

x + y = 7 -> x = 7 - y (break out x/make x alone)
2.50x + 3.50y = 21.50 -> x + 1.4y = 8.6 (divide by 2.50)

Substitute x (in x + 1.4y = 8.6) and solve for y
7 - y + 1.4y = 8.6 -> 0.4y = 1.6 -> y = 4

y = number of chicken orders = 4

Substitute y (in x = 7 - y) and solve for y
x = 7 - 4 = 3

x = number of pizza orders = 3

Answer 10

wow thank you the answer is 4 for how many ordered chicken

Answer 11

Yw :)
