I just took the test. The answer is y=250(4^x)
30 is the answer because 30*25=750
1 pound = 16 ounces
1 ton = 2,000 pounds
3(6/8−1/2)+0.25
Rewrite 6/8 and 1/2 to have common denominators:
1/2 = 4/8
Now you have
3(6/8−4/8)+0.25
Simplify inside the parenthesis first:
3(2/8) +0.25
2/8 reduces to 1/4"
3(1/4) +0.25
Multiply 3 and 1/4:
0.75 + 0.25
Now add to get the final answer, which is 1.00
