The answer is (3 + m) - 7
7 is outside of the brackets because the problem states to subtract 7 after you add 3 and m, so to go according to PEMDAS we have to place 3 and m inside the brackets to tell us to do the addition first.

Answer:

38.4

38.4 is 48% of 80

What is 48% of 80?

Y is 48% of 80

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 48% * 80

Converting percent to decimal:

p = 48%/100 = 0.48

Y = 0.48 * 80

Y = 38.4
