Let x be the number of friends.
He wants to give out 2x bars and have 10 left and he has 16 bars so the expression is:-
2x + 10 = 16
now he can solve for x to find the number of friends he can treat.
F(1)=4(1+1+7)-2(1)+8-4
f(1)=36+2
f(1)=38
f(2)=4(2+2+7)-2(2)+8-4
f(2)=44
Total number of problems Nicole will have completed: y
Number of nights she studies: x
She has already completed 20 practice problems:
When x=0, y=20
She plans on completing 6 more problems each night:
y=20+6x
y=6x+20
Please, see the attached graph.
Thanks.
Given:
5 bonds of face value of 1,000 that paid 5% annual interest rate.
5 bonds x 1,000 = 5,000
5,000 x 5% x 1 year = 250
The total annual interest income of James is 250. Each bond earns 50 per annum.
