Marcus goes to the grocery store to buy some vegetables. He it's 3 pounds of tomatoes costing $0.90. Per pound, 1 pound of carrots costing $1.30 per pound, and 4 pounds of squash costing $1.45 per pound. How much did he spend on vegetables?

$8.00

Step-by-step explanation:

To find out how much 3 lbs of tomatoes cost, we will use the equation;

.90 divided by 3, which turns out to be .30. Meaning, each tomato costs .30.

1 pound of carrots is $1.30 per pound so that is self explanitory.

and to figure out how much 4 lbs of squash costing 1.45 per pound is simple;

4 x 1.45 = 5.80. Therefore, the cost os 4 lbs of squash is $5.80.

Adding up the costs of each ingredient, we get;

.90 + 5.80 + 1.30 = $8.00

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
