Answer:
$89.15
Step-by-step explanation:
50/4= 12.50
12.50+76.65= 89.15
Answer:
About $4.46
because you can't pay 4.466666667
Step-by-step explanation:
6 people
4 tacos------$5.00
2 burgers--$5.30
4 fries-------$9.00
6 juices-----$7.50
_______________
food ---------$26.80
divide $26.80 by the number of people so 6 then you get 4.466666667 and have to round up
Answer:
2
Step-by-step explanation:
Answer:
f(9.5) = 558.02.
Step-by-step explanation:
Because it is an exponential function, it can be written: y = (a)(b)^x
Now substitute in the two known points:
72 = (a)(b)^7.5 and
2 = (a)(b)^4 : => since 2 = (a)(b)^2 divide the left side by 2 and the right by (a)(b)^2
72/2 =[(a)(b)^7.5]/[(a)(b)^4]: => the (a) cancels out and b becomes b^(7.5–4)
36 = b^3.5: => To isolate b take the 3.5 root of both sides
{3.5 root}(36) = {3.5 root}(b^3.5)
2.783927 = b
Now to solve for a
2 = (a)(b)^4 => 2 = (a)(2.783927)^4 => 2 = (a)(60.066375) divide both sides by 60.066375 0.0332965 = a
Equation: y = (0.0332965)(2.783927)^x
Now plug in 9.5 for x
(0.0332965)(2.783927)^9.5 = 558.0178525 = 558.02
