Paul, Colin and Brian are waiters. One night the restaurant earns tips totalling £78.40.
They share the tips in the ratio 2:1:5.
How much more does Brian get over Colin?

Let 2x = Paul

Let x = Colin

Let 5x = Brian

2x + x + 5x = 78.40

8x = 78.40

x = 78.40 ÷ 8

x = 9.8

Brian gets 5(9.8) which is 49.

Colin gets 9.8.

Brain over Colin means 49/9.8 = 5.

Brain gets £5 more than Colin in terms of a tip.

sure i'm up for it

step-by-step explanation:

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}
