A total of 700 tickets were sold for a game for a total of $3420. If adult tickets sold for $7 each and child tickets cost $3 each, how many of each kind of ticket were sold?

330 tickets sold to adults

370 tickets sold to children

Explanation:

Suppose:

Number of Tickets

Adult = A

Child = C

According to given condition

A + C = 700 (Eq 1)

7A + 3C = 3,420 (Eq 2)

By multiplying (Eq 1) with 3 we get

3A + 3C = 2,100 (Eq 3)

By subtracting (Eq 3) from (Eq 1)

7A + 3C - (3A + 3C) = 3,420 - 2100

7A - 3A + 3C -3C = 1320

4A = 1320

A = 1320/4

A = 330

Putting value of A in (Eq 1)

330 + C = 700

C = 700 - 330

C = 370

Check:

(7x330) + ( 3x370) = 3420

2310 + 1110 = 3420

3420 = 3420

in 2001, dell computer became the world’s largest personal computer vendor, continuing to

gain market share and post profits in an industry struggling with slumping sales and billions of

dollars in losses. dell sells 90% of its pcs directly to the final customer, largely bypassing the

reseller channel that accounts for most of the world’s pc sales. this direct customer relationship

is the key to dell’s business model, and provides distinct advantages over the indirect sales

model. dell’s direct relationship with the customer allows it to tailor its offerings to customer

needs, offer add-on products and services, and use the internet to offer a variety of customer

services. in addition, dell’s pcs are built to customers’ specifications upon receipt of an order,

giving dell additional advantages over indirect pc vendors who must try to forecast demand and

ship products based on those forecasts. dell’s direct sales and build-to-order model has achieved

superior performance in the pc industry in terms of inventory turnover, reduced overhead, cash

conversion, and return on investment (kraemer, et al., 2000).

explanation:
