A T- shirt costs $5.99. a. How much will you spend if you buy x T-Shirts?

b. Evaluate your expression to calculate the amount of money you will spend if you buy 4 shirts or 10 shirts.

a. c = 5.99x

c = total cost

x = amount of t - shirts

b. 4 shirts: $19.96

10 shirts: $49.90

Step-by-step explanation:

plug in 4 for x:

c = 4.99(4)

c = 19.96

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}
