Answer:
-20
Step-by-step explanation:
32-12=20 so do it backwards. :D
Answer:
Step-by-step explanation:
Step one:
given
cost per drive= $20
additional fee per person= $4
let the number of persons be p
and the total cost be C
The total cost function is expressed as
Step two:
Required:
<u><em>We want to make P subject of the cost function </em></u>
Take 20 to the other side we have
C-20=4p
divide through by 4
P=C-20/4
simplify
P=C/4-5
Answer:
Donny's bagels is the better deal.
Step-by-step explanation:
Bob's bagels are 10 for $11
Unit price for Bob's bagels = $11 / 10 bagels = $1.10 per bagel
Donny's bagels are 4 for $3
Unit price for Donny's bagels = $3 / 4 bagels = $0.75 per bagel
because Donny's unit price is less than that of Bob's (i.e each of Donny's bagels cost less than each of Bob's bagels), thus Donny has the better deal
Answer:
Ok, I have 2 answers
1. Use Desmos to solve for them or
2. For one of them the y-intercept is 4 so you begin the line at 4 and you go up 2 over 1. For the second -3.5 is the y-intercept so start at -3.5 and go down 1 over 1.
10m=10-5(m-7)
10m=10-5m+35
10m=45-5m
15m=45
m=3
