Valeria already owns 147 necklaces, and additional necklaces are priced at 2 for a dollar. How much money does Valeria need to spend on new necklaces in order to own a total of 477
necklaces? Write and solve an equation to find the answer

$660

Step-by-step explanation:

Step 1

The number of extra necklaces that valeria needs is calculated as:

477 necklaces - 147 necklaces

= 330 necklaces

Step 2

We are told that

1 extra necklace cost $2

Hence

1 necklace = $2

330 necklaces = x

Cross Multiply

x = 330 × $2

x = $660

Therefore, Valeria need to spend and additional $660

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
