Transcribed Image Text:Write an algebraic equation for the
following problem and then solve it.
A landscaping company needs 200
gallons of 18% fertilizer to fertilize the
shrubs in an office park. They have in
stock 25% fertilizer and 15% fertilizer.
How much of each type should they

Let x = the number of gallons of 25%
fertilizer to be used. Write
an expression, in terms of x, that is
equal to "200 gallons of 18% fertilizer".
= 0.18(200)
(Use integers or decimals for any
