Marcos is in charge of counting cans for the food drive. He organizes the cans in 6-by-8 arrays, and he has 10 of these arrays.
V125BC [204]

Answer:

The final answer is NO, i.e. He does not have at least 500 cans.

Step-by-step explanation:

He organizes the cans in 6-by-8 arrays.

The number of elements in the array can be found by finding the multiplication of its Rows numbers with its Columns numbers.

Given the array is of order 6-by-8. So the elements in the array = 6x8 = 48 elements.

And he has 10 of these arrays. So total cans = 48 x 10 = 480 cans.

Hence, the final answer is NO, i.e. He does not have at least 500 cans.

Please help me with these questions 19pts
jeka57 [31]

Answer:

a)

p(r)=(r-5)\cdot 1.05

b)

p(15.50)=(15.50-5)\cdot1.05=10.50\cdot1.05=11.025\approx11.03\ \$

Step-by-step explanation:

a)

Assume that r is a regular price before discount and tax

Including discount, we substract 5 from r. We get (r-5).

Then, we include tax by adding 5% value of (r-5)

Including a tax we may realize by multiplying initial value (r-5) by 1.05, where an ending .05 is percentage value of a tax

b)

in a formula p(r)=(r-5)\cdot 1.05 we substitute r=15.50  and calculate the value on the right side of the sign "=".

You solve it too, using a calculator.

If you push the following buttons:

1 5 . 5 0 - 5 = + 5 %

you should get a result 11.025, after approximation to the 2 digits after comma there is 11.03
