Answer:
53
Step-by-step explanation:
42/6=7
7*5=35
18+35=53
It would be e, because it went down 10 instead of 5
1/2 is equivalent to 2/4 because,
2(1/2) = 2/4
So as you can see if you multiply the numerator(top) and the denominator(bottom) by the same number, you get an equivalent fraction! In my example you can see that I multiplied both by 2.
800(1+7)∧4
it will be $1048.63
