4) ming and carlos are selling cookie dough for a school fundraiser. customers can buy
packages of chocolate chip cookie dough and packages of gingerbread cookie dough.
ming sold 8 packages of chocolate chip cookie dough and 12 packages of gingerbread
cookie dough for a total of $364. carlos sold 1 package of chocolate chip cookie dough
and 4 packages of gingerbread cookie dough for a total of $93. find the cost each of
one package of chocolate chip cookie dough and one package of gingerbread cookie
dough.

Using the 2nd equation for substitution in the 1st equation:

c + 4g = 93

c = (93-4g)

8(93-4g) + 12g = 364

744 - 32g + 12g = 364

-32g + 12g = 364 - 744

-20g = -380

g = -380/-20

g = +$19 for the ginger cookie dough

then

c = 93 - 4(19)

c = $17 for the chip dough

Step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
