You are buying flowers and soil for the garden at the senior center. The flowers cost $6, each and the soil $40. You have $130 to purchase the soil and flowers. What is the greatest number of flowers that you can purchase?

15 flowers

Step-by-step explanation:

Make an equation

We know that we have to buy soil and flowers cost $6, but we don't know how many flowers.  Everything must equal $130.

6x+40=130

Subtract 40 from both sides

6x=90

Divide by 6 on both sides

x=15

The greatest number of flowers you can purchase is 15

Hope this helps! :)

62

Step-by-step explanation:

t=digit in the tens place

u=digit in the units place

t=3*u

original number=t*10+u

number with reversed digits=u*10+t

u*10+t=t*10+u-36

u*10+(3*u)=(3*u)*10+u-36

10u+3u-30u-u=-36

-18u=-36

u=2

t=3*u=6

Original number = 62

Check the solution:

6=3*2 ok

26=62-36 ok
