Martin combined different amounts of orange juice, pineapple juice, and strawberry juice to make 1850 milliliters (ml) of fruit punch. The amount of orange juice combined was x ml. The amount of pineapple juice combined was 100 ml more than the amount of orange juice, and the amount of strawberry juice was half the amount of orange juice. This is represented in the equation below:x + (x + 100) + one half x = 1850 What was the difference in the amounts of pineapple juice and strawberry juice Martin combined?

Find the value of I given that p=300, r=0.14, and t=2

Answers

Hi there, Convert r percent to r a decimal, r=R/100=0.14%/100=0.0014 per year. Now, we have to solve using a equation, the equation is A=300(1+(0.0014*2))=300.84, Therefore, the answer is $300.84

300x0.14=0.42
0.42x2=0.84

If y varies directly as x, and y is 6 when x is 72, which is the value of y when x is 8 ?

Answers

$(y)/(x) = k$

$(6)/(72) = k$

$(1)/(12) = k$

********************************

$(y)/(x) = k$

$(y)/(8) = (1)/(12)$

12y = 8

$y = (8)/(12)$

$y = (2)/(3)$

y = $(2)/(3)$

given y ∝ x

To convert to an equation multiply by k the constant of variation

y = kx

to find k use the given condition y = 6 when x = 72

y = kx ⇒ k = $(y)/(x)$ = $(6)/(72)$ = $(1)/(12)$

equation is → y = $(1)/(12)$ x

when x = 8 then

y = $(1)/(12)$ × 8 = $(8)/(12)$ = $(2)/(3)$

I need an equation for this problem: A small golf club manufacturer is concerned about their monthly costs. The shop has fixed costs of $23,250 per month to run in addition to the $145 in materials per set of golf clubs produced. If the company wants to break-even making 100 sets of clubs per month, what should they charge for each set? Recall that the break-even point is when revenue equals costs. I solved it and the answer is 377.50 but i need a proper equation for my answer
