Question

PLS HELP ME THIS IS HARD

Answer 1

Answer:

1 dollar is equal to 0.75 E

Step-by-step explanation:

120$ = 90 e -----> 4$ = 3E

250$ = 187.50 e -----> 4$ = 3E

400$ = 300 e -----> 4$ = 3E

----------------------------------

from this we know 4$ = 3E

1 E = 4$/3

1 E = 1.33...$

---------------------

1 $ = 3/4 E

1 $ = 0.75 E

---------------------

1.33...$ dollars is equal to 1 E and

1 $ is equal to 0.75 E

-----------------------------------

90 x 1.33... =120

187.50x1.33...= 250

300 x 1.33... = 400
