Yoku is putting on sunscreen. He uses 2ml to cover 50cm^(2) of his skin. He wants to know how many milliliters of sunscreen (c) he needs to cover 325cm^(2) of his skin. How many milliliters of sunscreen does Yoku need to cover 325cm^(2) of his skin? ml

Establish Relationship: First, let's establish the relationship between the amount of sunscreen used and the area it covers. Yoku uses 2 ml of sunscreen to cover 50 cm² of skin. We need to find out how many milliliters of sunscreen are needed to cover 325 cm² of skin. We can set up a proportion to solve for the unknown quantity (c), which represents the amount of sunscreen needed for 325 cm².Set Up Proportion: Using the proportion, we have: 2 ml / 50 cm² = c ml / 325 cm² Now we need to solve for c by cross-multiplying. 2 ml * 325 cm² = c ml * 50 cm²Cross-Multiply: Perform the multiplication on both sides of the equation: 650 ml*cm² = 50c ml*cm² Now, divide both sides by 50 cm² to isolate c. 650 ml*cm² / 50 cm² = cIsolate c: Calculate the division to find the value of c: c = 650 ml*cm² / 50 cm² c = 13 ml So, Yoku needs 13 milliliters of sunscreen to cover 325 cm² of his skin.

Establish Relationship: First, let's establish the relationship between the amount of sunscreen used and the area it covers. Yoku uses $2\,\text{ml}$ of sunscreen to cover $50\,\text{cm}^2$ of skin. We need to find out how many milliliters of sunscreen are needed to cover $325\,\text{cm}^2$ of skin. We can set up a proportion to solve for the unknown quantity $(c)$ , which represents the amount of sunscreen needed for $325\,\text{cm}^2$ .
Set Up Proportion: Using the proportion, we have: $\newline$ $\frac{2 \, \text{ml}}{50 \, \text{cm}^2} = \frac{c \, \text{ml}}{325 \, \text{cm}^2}$ $\newline$ Now we need to solve for $c$ by cross-multiplying. $\newline$ $2 \, \text{ml} \times 325 \, \text{cm}^2 = c \, \text{ml} \times 50 \, \text{cm}^2$
Cross-Multiply: Perform the multiplication on both sides of the equation: $\newline$ $650 \, \text{ml} \cdot \text{cm}^2 = 50c \, \text{ml} \cdot \text{cm}^2$ $\newline$ Now, divide both sides by $50 \, \text{cm}^2$ to isolate $c$ . $\newline$ $\frac{650 \, \text{ml} \cdot \text{cm}^2}{50 \, \text{cm}^2} = c$
Isolate c: Calculate the division to find the value of c: $\newline$ $c = \frac{650 \, \text{ml} \cdot \text{cm}^2}{50 \, \text{cm}^2}$ $\newline$ $c = 13 \, \text{ml}$ $\newline$ So, Yoku needs $13 \, \text{milliliters}$ of sunscreen to cover $325 \, \text{cm}^2$ of his skin.
