Admission to a home and garden show cost $7 per person during the week and $9 per person on the weekend. During one week of the
show, a total of $142,506 was paid in admission. This situation can be represented by the equation 7x+9y=142,506 where x is the number of tickets sold during the week and y is the number of tickets sold on the weekend.
For b) you already have two possibilities, since you have the intercepts. <span>(20358, 0) and (0,15834) are two possible points, although not very likely. </span>
<span>Solve for y: y= (-7/9)x + 15834 </span>
<span>Any multiple of 9 will give whole number answers. </span>
Each football is sold for $9.95. To make one of these football costs $7.10. There is a profit of $2.85. Divide 11,400 by 2.85 to see how many footballs would have to sell to break even.
11,400 / 2.85 = 4000.
4000 footballs would have to be sold to break even.
