Find 30% of 70<br> a. 21<br> b. 36<br> c. 40

gtnhenbr [62]

A is your answer

We can cross multiply using x/70=30%/100

Solving it we get:
100x=2100 (70 times 30)
x=21

So we get a, 21 as your answer.

I hope this helped!

1. Your cereal company wants to make a family size box for your most popular brand. Your current, 17 ounce, box costs $1.50 to f

HACTEHA [7]

Answer:

The cost to fill the new family size box will be $\$2.93$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

we have

$z=1.25$

$z^{3}=1.25^{3}=1.953125$

To find the new cost multiply the original cost by the scale factor elevated to the cube

$\$1.50(1.953125)=\$2.93$

The new volume would be

$17(1.953125)=33.20\ ounces$
