Lenny wants to buy a lawn mower priced at $266, if he pays cash. He can buy it on credit for 4 payments of $72.

What is the total cost if Lenny buys the lawn mower on credit?

Answer

--Percent means out of 100, so 20% = 20/100

The prob in other words is asking

 --  $60 is 20% of what number?

'$60'   --          --->  60

'is'       --          --->  =

20%    --         ---> 20/100

'of'     --            ---> * (multiply)

'what number'  ---> x  (variable)

288

Step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
