Ariel made cupcakes to sell. 2/3 of them were chocolate chip,25% of the reminder was strawberry and the rest were 90 vanilla cup

Anton [14]

Answer:

Let x be the total number of cupcakes.

Chocolate chips =

$\frac{2}{3} x$

Strawberry =

$\frac{1}{4} \times \frac{1}{3} \\ = \frac{1}{12} x$

Vanilla =

$x - \frac{2}{3} x - \frac{1}{12}x \\ = \frac{1}{3} x - \frac{1}{12} x \\ = \frac{1}{4} x$

given

$\frac{1}{4} x = 90$

$x = 90 \div \frac{1}{4} \\ = 90 \times 4 \\ = 360$

a)Number of Chocolate chip Cupcakes =

$\frac{2}{3} \times 360 \\ = 240$

b)Number of Strawberry cupcakes =

$\frac{1}{12} \times 360 \\ = 30$

11. A customer purchases a stroller and packs of diapers from a store. The table shows the total

bixtya [17]

Answer:

f(x) = 25x + 400

Step-by-step explanation:

Here, we want to find the relationship between the number of diaper packs and the total cost

From what we have in the options, we can see a linear relationship;

Since it is a linear relationship, it can be modeled using the equation;

y = mx + b

where m is the slope and b is the y-intercept

From what we have, we can identify the following parts;

where x represents number of diaper packs and f(x) or y represents total cost

The points identifiable are as follows;

(2,450) , (6,550) and (10,650)

The slope will be;

(550-450)/(6-2) = 100/4 = 25

So we have the equation partially as;

y = 25x + b

To get b, we can use any of the points

Let’s use (2,450)

Thus, we have

450 = 25(2) + b

b = 450 - 50

b = 400

So the equation is;

y = 25x + 400

Thus;

f(x) = 25x + 400
