If the exchange rate is 1.5 U. S. dollars / 1 euro, how many U. S. dollars would be equivalent to 20 euros? A. $1.50

B. $18.50

C. $30.00

D. $13.30

The answer is C because 1 times 20 is 20 and .5 times 20 is 10 then you get 30

C.) $30.00

Step-by-step explanation: If 1.5 U.S. dollars equals 1 euro, then 1*20 would be 20 euros. So then, you could multiply 0.5*20 to get 10. Finally, you add $10 + $20 to get $30 U.S. dollars.

0.5*20= $10

20+10= $30

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
