Samuel wants to use his earnings from Monday and Tuesday to buy some batteries

IrinaK [193]

Answer: There are 2 batteries which he can buy with his earnings .

Step-by-step explanation:

Since we have given that

Selling price of cans at the recycling center = $0.40 per pound

Number of pounds of cans he sold on Monday = 16.2

Number of pounds of cans he sold on Tuesday = 11.8

Total earning of Samuel is given by

$(16.2+11.8)\times 0.40=\$11.2$

Now, cost of battery =$5.60

So, number of batteries he can buy is given by

$\frac{\text{ Total earnings}}{\text{ Cost of each battery}}\\\\=\frac{11.2}{5.6}\\\\=2$

So, there are 2 batteries which he can buy with his earnings .

Liz earns a salary of $2,000 per month, plus a commission of 8% of her sales. She wants to earn at least $2,500 this month. Ente

andrezito [222]

Answer: $2000 + 0.08s ≥ $2500

Step-by-step explanation:

The expression that will be used to calculate the earnings of Liz will be:

= b + (c × s)

Where:

b = base salary = $2,000

c = commission rate = 8% = 8/100 = 0.08

s = the sales that the commission rate will be applied against.

The inequality to find amounts of sales that will meet Liz goal will be:

= b + (c × s)

= $2000 + (0.08 × s) ≥ $2500

= $2000 + 0.08s ≥ $2500
