$\\ \rm\longmapsto 2^{4x+4}=64^{x+2}$

$\\ \rm\longmapsto 2^{4x+4}=(2^6)^{x+2}$

$\\ \rm\longmapsto 2^{4x+4}=2^{6(x+2)}$

$\\ \rm\longmapsto 4x+4=6(x+2)$

$\\ \rm\longmapsto 4x+4=6x+12$

$\\ \rm\longmapsto 4-12=6x-4x$

$\\ \rm\longmapsto -8=2x$

$\\ \rm\longmapsto x=\dfrac{-8}{2}$

$\\ \rm\longmapsto x=-4$

Joseph's lunch at a restaurant costs 13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax

Musya8 [376]

Answer:

The cost before tax with tip is $15.21.

Step-by-step explanation:

To calculate percentage, take the percent (17%) and take its decimal form. This means 17% is 0.17 (like 50% would be 0.5). multiply the number you want the percentage of by the decimal form. 13*0.17=2.21. Add this to the cost before tax and before tip. 13.00+2.21=15.21. The cost before tax with tip is $15.21.
