Question

Every yard Johnnie mows he earns $7
how many yeards will he have to mow to have no more than $900 in his account
make a table with 3 collumns

Answer 1

To find out how many yards Johnnie can mow for no more than $900, we can start with the following formula:

\[
\text{Total Earnings} = \text{Number of Yards Mowed} \times \text{Earnings per Yard}
\]

In this case:

- Total Earnings = $900
- Earnings per Yard = $7

We need to determine the maximum number of yards Johnnie can mow without exceeding $900.

### Calculation:
\[
\text{Number of Yards Mowed} = \frac{\text{Total Earnings}}{\text{Earnings per Yard}} = \frac{900}{7} \approx 128.57
\]

Since Johnnie can't mow a fraction of a yard, we'll round down to 128 yards.

### Table:

| Number of Yards Mowed | Earnings ($) | Total Money in Account ($) |
|------------------------|--------------|-----------------------------|
| 0 | 0 | 0 |
| 10 | 70 | 70 |
| 20 | 140 | 140 |
| 30 | 210 | 210 |
| 40 | 280 | 280 |
| 50 | 350 | 350 |
| 60 | 420 | 420 |
| 70 | 490 | 490 |
| 80 | 560 | 560 |
| 90 | 630 | 630 |
| 100 | 700 | 700 |
| 110 | 770 | 770 |
| 120 | 840 | 840 |
| 128 | 896 | 896 |
| 130 | 910 | 910 | (exceeds $900)

### Conclusion:
Johnnie can mow a maximum of **128 yards** to have no more than **$900 in his account**.
