Frida has a $215 for her graduations party at fun and game palace. the general party fee is $75 and a $7 charge is added for each guest, not including frida. how many guests can frida invite without going over her budget?

if you do the equation $75+7x=$215  you would subtract 215-75 and get 140 then divide 140 divided by 7 and you should get 20 guests

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

step-by-step explanation:

the answer is 128
