Answer:

$2.50 coupon is better as it gives a cheaper sale price.

Step-by-step explanation:

Price of good = $12

Sale price = price of good - coupon

Coupon 1 :

$2.50

Sale price = $12 - $2.50 = 9.50

Coupon 2:

15% off

Sale price =. (100 - 15)% * 12

= 0.85 * 12

= $10.2

Answer:

144 children and 170 adults

Step-by-step explanation:

make 2 equations

make :

the children as the regarded as the variable : x

the adults are the regarded as the variable  : y

<em>5x + 6 y = 1740</em>

<em>x + y = 314</em>

<h3><u>solve this by the method of elimination </u></h3>

5x + 6y = 1740

5(x + y = 314)

= 5x + 5y = 1570

5x + 6y = 1740

5x + 5y = 1570

the 5x is cancelled out

6y - 5y = 1740 - 1570

y = 170

now replace the value of y in the eqaution

5x + 6 (170) = 1740

5x =720

x = 144

hence they were 144 children and 170 adults

mark as brainiest
