You purchase two bottles of sunscreen and a hat. the hat costs$6.50. you pay 6% sales tax. you pay a total of $16.43. how much does one bottle of sunscreen cost?

Solution:

Let the bottle of  sunscreen cost be $x. Then we can write

($x+ $6.50)+6%($x+ $6.50)=$16.43

Now solve this for x as below

Hence the  bottle of sunscreen cost $9.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
