g An increase in the interest rate: has no effect on investment. may be caused by a drop in investment demand. increases planned investment because people who make money from interest have more money to invest. reduces planned investment because the interest rate is the cost of borrowing to finance investment projects.

reduces planned investment because the interest rate is the cost of borrowing to finance investment projects.

Explanation:

There is an inverse relationship between interest rate and planned investment.

The higher interest rate is, the lower planned investment. This is because interest rate is the cost of borrowing. An higher interest rate means the cost of borrowing would increase.

On the other hand, a lower interest rate increases planned investment. This is because a lower interest rate means that the cost of borrowing would reduce.

4,000 rosebushes

Explanation:

Given that,

Cost of acquire licensing rights(fixed cost) = $6,000

Selling price of each right = $6

Per-unit variable cost = $3

Profit = $6,000

Contribution per unit = Sales - Variable cost

                                   = $6 - $3

                                   = $3 per unit

Total contribution units produce and sold = Contribution per unit × units sold

                                                                      = $3 x units produce and sold

Profit = Contribution - Fixed cost

$6,000 = ($3 x units produce and sold) - $6,000

$12,000 = $3 x units produce and sold        

                                                 = 4,000 units

Therefore, 4,000 rosebushes have to be produce and sold in order to make a profit of $6,000.
