Joe sold a total of 10 baked goods. Each cookie costs $1.25 and each brownie costs $2.50. Joe made $20 at the bake sale. How man

AURORKA [14]

Answer:

4 cookies

Step-by-step explanation:

Let the number of cookies he sold be c and that of brownies be b.

Assuming that brownies and cookies are the only type of baked goods sold,

b +c= 10 -----(1)

Amount of money received= $20

b(cost of brownie) +c(cost of cookie)= $20

2.50b +1.25c= 20 -----(2)

From (1): b= 10 -c -----(3)

Substitute (3) into (2):

2.50(10 -c) +1.25c= 20

Expand:

2.50(10) +2.50(-c) +1.25c= 20

25 -2.50c +1.25c= 20

-1.25c +25= 20

Being constants to 1 side:

-1.25c= 20 -25

-1.25c= -5

c= -5 ÷(-1.25)

c= 4

Thus, Joe sold 4 cookies.

Here is a garden and a pond.

Anna11 [10]

Answer:

<h2>Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.</h2>

Step-by-step explanation:

You can observe a representation of this problem in the image attached.

Notice that the grass seed is gonna be put only in the green zone, out of the pond. So, we need to find each area and subtract them.

$A_{garden}= 14 \times 9 =126 \ m^{2} \\A_{pond}=2.4 \times 3.8 = 9.12 \ m^{2}$

The difference is

$A_{seed}=126 - 9.12 = 116.88 \ m^{2}$

Now, according to the problem, one box of grass seed covers 15 meters of the garden, let's divide this number with the seed area.

$n=\frac{116.88}{15} \approx 7.792$

Therefore, Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.
