Answer:

Mrs Clark spends in total $119 on rose bushes.

Step-by-step explanation:

Here, the total length that needs to be covered  = 13 ft

The distance between 2 consecutive rose pant = 2 ft

Cost of planting each bush = $17

Now, if we plant first plant at 1 feet,

Then the second bush will be planted at a distance of 2 ft  + 1 ft = 3  ft

Third bush  = Second Bush  +  2 ft  = 3 ft +  2 ft  = At   5 ft

Fourth bush  = Third Bush  +  2 ft  = 5 ft +  2 ft  = At   7 ft

Fifth bush  = Fourth Bush  +  2 ft  = 7 ft +  2 ft  = At   9 ft

Sixth bush  = Fifth Bush  +  2 ft  = 9 ft +  2 ft  = At   11 ft

And, lastly Seventh bush  = Sixth Bush  +  2 ft  = 11 ft +  2 ft  = At   13 ft

So, as to cover a total of 13 ft, 7 bushes are planted in total which are 2 ft apart from one another.

Now, cost of planing 7 rose bushes  = 7 x ( Cost of planting 1 rose bush)

= 7 x ($17)  = $119

Hence, Mrs Clark spends in total $119 on rose bushes.
