Which inequality can be used to represent this problem? (HELP ASAP, IM TIMED)

Nadya [2.5K]

Propane costs $3.50 per hundred pounds,

and there is a $6 monthly delivery fee.

A family has budgeted $85 for their propane this month.

Let 'x' hundreds of pounds can the family use without going over budget

Here family has budgeted $85 for their propane.

So the cost for Propane = $ 3.5x

One month delivery fee $6

Therefore cost + delivery charge not exceed $85

So 3.5x + 6 ≤ 85

3.5x=85-6 =79

x = 22.57

Therefore 22 hundreds of pounds can the family use without going over budget

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$4000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &2 \end{cases} \\\\\\ A=4000\left(1+\frac{0.08}{1}\right)^{1\cdot 2}\implies A=4000(1.08)^2\implies A=4665.6$
