Tj earns a 20% commission on all sales plus a base salary of $40,000. his total income last year was more than $70,000. which inequality can be used to calculate the minimum number of tj's sales? 40,000 - 0.2 > 70,000 0.2 + 40,000x > 70,000 70,000 + 0.2x > 40,000 40,000 - 0.2x > 70,000

40,000 + 0.2x ≥ 70,000

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
