Step 1: Given details are cost of cashews = $1.58, cost of walnuts = 78 cents = $0.78, total weight of nuts = 40 pounds, cost of nuts per pound = $1.50

Step 2: Let number of pounds of cashews to be mixed be C, then number of pounds of walnuts will 40 - C. Form equation with these variables.

⇒ 1.58 C + (40-C) 0.78 = 40 × 1.50

⇒ 1.58 C + 31.2 - 0.78 C = 60

⇒ 1.58 C - 0.78 C = 60 - 31.2

⇒ 0.8 C = 28.8

⇒ C = 36 pounds

⇒ Number of pounds of walnuts = 40 - C = 4 pounds

Answer:

$n = 12h$

Step-by-step explanation:

Given

$r = 12/hr$ --- rate

$h \to hours$

$n \to amount$

Required

Determine which solution is correct or incorrect

The solutions are not given. So, I will provide a general explanation

The amount (n) is calculated as:

$n = r * h$

So, we have:

$n = 12 * h$

$n = 12h$

The above is the general equation to solve for the amount, given h hours

When h = 2.5, we have:

$n = 12*2.5$

$n = 30$
