Class Gayle and Ernie are going to sell canv
backpacks.
They spend $75 for a used sewing
machine and estimate the canvas will
cost $15 per backpack. They plan to
sell the backpacks for $ 40
Write and solve an inequality to find
when they will start making a profit.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

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:

answer: b f g .
