marishachu [46]

Answer:

The number of wreaths Alaina sells is 9 .

Step-by-step explanation:

As given

Alaina is selling wreaths and poinsettias for her chorus fundraiser.

Wreaths cost $27 each poinsettia cost $20 each.

If she sold 15 poinsettias and made $543.

Let us assume that the number of wreaths Alaina sells = x

As the number of poinsettias Alaina sells = 15

Than the equation becomes

27x + 15 × 20 = 543

27x + 300 = 543

27x = 543 - 300

27x = 243

$x = \frac{243}{27}$

x = 9

Therefore the number of wreaths Alaina sells is 9 .

wolverine [178]

Answer:

$x=216 salads$

Step-by-step explanation:

One Hour:

Salad=40

Sandwich=19

Total work time $T=7$

Generally

Time to make 30 sandwiches is

$T_s=\frac{30}{19}$

$T-s=1.6hours$

Therefore

Bill has 7-1.6 hours to make salads and can make x about of salads in

$x=(7-1.6)*40$

$x=5.4*40$

$x=216 salads$
