Question

12. Lyla has $150 to purchase shrubs for her front yard. Small shrubs cost $20

per shrub and large shrubs cost $35 per shrub.
Part A: Write an equation that can be used to determine the number of small
shrubs, x, and the number of large shrubs, y that Lyla can purchase.

Answer 1

20x+35y=150

A) Since Lyla has $150 to buy shrubs, and the small ones cost $20, and the large ones $35, we can write out the following equation

`\begin{gathered} \\ 20x+35y=150 \end{gathered}`

Note that, we need to find the number of shrubs altogether in order to set another equation and solve this linear system.

In addition to this, this equation relates the cost of each shrub and the total expenditure.

Thus, the equation for Part A is 20x+35y=150
