Quality Grocer makes its own bulk "trail mix" by mixing raisins and peanuts. The wholesale cost of raisins is $3.75 per kg and the cost of peanuts is $2.89 per kg. To the nearest 0.1 kg, what amounts of peanuts and raisins should be mixed to produce 50 kg of trail mix with an effective wholesale cost of $3.20 per kg?

When N = $135 and d = .085, the result of $\frac{N}{1+d}$ is $124.42.

Using the formula I = Pr t, solve for P given r=0.30, t=6 and I=$25.50 to the nearest cent.

Evaluate and calculate to the cent: $\frac{S}{(1+i)^{n}}$ for S = $850, i = 0.0075. n = 6

Evaluate the following, given R = 725, I = .076, n = 4 $\frac{R}{i}\left[1+\frac{1}{(1+i)^{n}}\right]$

What amount is 30% less than $300?

Evaluate the following: $\frac{1-1.056^{-15}}{0.056}$

Evaluate: 3d² - 4d + 15 for d = 2.5

Evaluate to six-figure accuracy: $\frac{1-1.0225^{-20}}{0.0225}$

Calculate the result to four decimal places given r = 1.3 and t = 2.6 $\frac{5 r^{6} t^{8}}{\left(7 r^{2} t\right)^{4}}$

Solve for x to five-figure accuracy: $3 x\left(1.03^{5}\right)+\frac{x}{1.03^{3}}+x=\frac{\$ 2500}{1.03^{2}}$

Calculate the final result to two decimal places, where x = $6.80 $\frac{3 x}{1.065}+\frac{8.3 x}{13}+.07(8.8 x-20)$

Simplify and collect like terms: $\frac{2 x+9}{4}-1.2(x-1)$
