Question

at fumikos fish market, it costs $9 for 2 kilograms of tuna. at this rate, how much does it cost for 10 kilograms of tuna?
(a) let c be the unknown cost of tuna (in dollars). using the values below, create a proportion that can be used to find c.
values: c, 9, 2, 10
(b) use the proportion from part (a) to find the cost of 10 kilograms of tuna. do not round any computations.
$

Explanation:

Step1: Set up cost-weight proportion

$\frac{C}{10} = \frac{9}{2}$

Step2: Solve for C via cross-multiplication

$C = \frac{9 \times 10}{2}$

Step3: Calculate final cost

$C = 45$

Answer:

(a) $\boldsymbol{\frac{C}{10} = \frac{9}{2}}$
(b) $\boldsymbol{45}$
