2. how much in dollar will the sales amount to the of his journey back to USA ​

4166.67$

Step-by-step explanation:

1920 x 250 = amount

Amount = 120%

Cost price = 100%

1920 x 250= 120%

Cost price = 100%

Cross multiply and divide both side by 120

1920 x 250 x 100/120 = price

Exchange rate = cost in #/cost in $

= (1920 x 250 x 5/6)/(5000)

= (96 x 5/6) = 16 x 5= 80

Exchange rate then was 80 to 1$

The sales will be 400000/96 = 4166.67$

1. $1:#80

2.$5000

Step-by-step explanation:

ok... lots of moving parts here

$5000 / 250 = $20 per lantern.

x (1 + .2) = 1920

x = 1600

$5000 : (1600*250)

$5,000:#400,000

c

sales back to the us at $1:#96

1920*250 = 480000

#480000/#96=$5000

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857
