Answer:
$525
Step-by-step explanation:
Shirley pays the other 50%, so pays ...
0.50 · $1050 = $525
Here, you just want to solve for b. because the right side of the equation doesn't have any like terms, you have to factor that b out:
s = ab - bc
s = b(a - c)
divide both sides by (a - c)
s/(a - c) = b is your answer. it's "s" over "a - c" if the formatting is difficult to read
The answer you are looking for could either be 16 or 40. To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.
Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.
OR
Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.
I'm not quite sure where the exponent was meant to go, but I hope this helps!
