To solve the problem “56 is what percent of 70?”, Noah uses the double number line below. On the double number line, write the correct numbers at each unlabeled tick mark. Then solve the problem.

80

Step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

$450 i think. hope this ☺
