jenyasd209 [6]

Answer:

It is better to buy 20 g of flour 3 for 3.50

Step-by-step explanation:

It is given that 20g of 3 for 3.50

It means 3 packets of 20 g is 3*20 =60

So, 60g is for 3.50

So, 1 g = $\frac{3.5}{60}$ =0.05833 per gram.

Now, let's find unit rate for 40 g of 2 for 9.

2 packets of 40 gram = 2* 40 =80 grams

So, 80 grams costs 9

So, 1 gram = $\frac{9}{80}$ =0.1125

So, it is better to buy 20 g of flour 3 for 3.50

uranmaximum [27]

(A) The customer that owns a 3-kW system exports 120 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

$120kWh\times\frac{\$3}{1kWh}=\$360$

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

$\$20+(120kWh\times\frac{\$0.06}{1kWh})=\$27.2$

(B) The customer that owns a 5-kW system exports 300 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

$300kWh\times\frac{\$3}{1kWh}=\$900$

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

$\$20+(300kWh\times\frac{\$0.06}{1kWh})=\$38$
