One electrician charges his customers a $60 service fee plus $35 per hour.
gavmur [86]

Answer:

2 hours; $130

Step-by-step explanation:

We can do this by setting up an equality since we are finding when they are the same. Say x is the number of horus:

65 * x = 60 + 35* x

30 * x = 60

x = 2 hours

The cost will be the same at two hours, and plugging it in, we can get 65*2=130.

If Will buys 1 kilogram of African rice and 2 kilograms of basmati rice, how much will he spend? brown rice $3.03/kg $3.59/kg st
Alenkasestr [34]

Answer:

Step-by-step explanation:

Sorry, because of lack of punctuation and organization, I cannot determine with any confidence the price per kilo of each of the rices.

He will spend the price of one kg of African rice plus twice the price of Basmati rice.

IF

African rice = $1.69/kg

and

Basmati rice = $3.05/kg

THEN

Cost = 1.69 + 2(3.05) = $7.79
