I NEED THIS ANWER ASAP Electric guitar kits originally cost d dollars online. You buy the kits on sale for 50% of the original price, plus a shipping fee of $4.50 per kit.
After painting and assembly, you sell each guitar online for (1.5d + 4.5) dollars. Find your profit on each guitar sold

your profit is Double the price that you bought the kits

Step-by-step explanation:

x= cost of kit

you buy it x/2

x/2 + 4.5 (1)

x + x/2 +4.5 (2)

let x = 40

40/2 + 4.5 = 24.5

40 + 40/2 + 4.5 = 64.5

64.5 - 24.5 = 40

so

you buy it in x/2 = 40/2 = 20

and sell it in x = 40

40/20 = 2

your profit is Double the price that you bought the kits

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
