Answer:
5. at least $62,000 worth of cars
6. $28,000 on sales
7. at least an 89
Step-by-step explanation:
5. We have a base salary of $1400 and the earning is 5% on sales (in other words, of the total profits from sales, the salesperson gets 5% of that). If s represents sales, we can say that the salesperson earns:
1400 + 0.05 * s
We want the end product to be at least $4500, so:
1400 + 0.05s ≥ 4500
0.05s ≥ 3100
s ≥ $62,000
The salesperson needs to sell at least $62,000 worth of cars.
6. This is similar to the previous question. Say the number of sales is s. Then, we have:
800 + 15% * s = 5000
800 + 0.15s = 5000
0.15s = 4200
s = 28,000
Ling needs to sell $28,000 on sales.
7. Let's say the last score is x. The average is found by adding all the test scores and dividing by the number of tests:
(85 + 76 + 94 + 81 + x) / 5 ≥ 85
336 + x ≥ 425
x ≥ 89
Latrell needs to earn at least an 89 on his next test to keep his average at 85 or higher.
