Question
Sasha solves a linear equation. Her work is shown below
$\begin{aligned} 2 x-3 & =\frac{x}{2}-5 \\ 2(2 x-3) & =x-5 \ldots \ldots \text { Step } 1 \\ 4 x-6 & =x-5 \ldots \ldots \text { Step } 2 \\ 4 x-x & =6-5 \ldots \ldots \text { Step } 3 \\ 3 x & =1 \ldots \ldots \text { Step } 4 \\ x & =\frac{1}{3}\end{aligned}$
Is Sasha's solution correct? If not, in which step did Sasha make an error?

Answer

No, Sasha's solution is not correct. She did an error in Step 1. She should transpose $\frac{x}{2}$ to LHS and -3 to RHS.

Sunscreens block harmful ultraviolet $\text{(UV)}$ rays produced by the sun. Each sunscreen has a Sun Protection Factor $\text{(SPF)}$ that tells you how many minutes you can stay in the sun before you receive one minute of burning $\text{UV}$ rays. For example, if you apply sunscreen with $\text{SPF}\ 15$, you get $1$ minute of $\text{UV}$ rays for every $15$ minutes you stay in the sun.
$1.$ A sunscreen with $\text{SPF}$ $15$ allows only$\frac{1}{15}$ of the sun’s $\text{UV}$ rays. What per cent of $\text{UV}$ rays does the sunscreen abort?
$2.$ Suppose a sunscreen allows $25\%$ of the sun’s $\text{UV}$ rays.
$a.$ What fraction of $\text{UV}$ rays does this sunscreen block? Give your answer in lowest terms.
$b.$ Use your answer from Part $(a)$ to calculate this sunscreen’s $\text{SPF}$. Explain how you found your answer.
$3.$ A label on a sunscreen with $\text{SPF}\ 30$ claims that the sunscreen blocks about $97\%$ of harmful $\text{UV}$ rays. Assuming the $\text{SPF}$ factor is accurate, is this claim true? Explain.
