Jenelle and three of her friends bought four smoothies for a total of three dollars. if she purchased smoothies on another day for her self and then 9 of her friends, how much money will she spend?

easy peasy

$3 divide by 4 smoothies to give you the price of each individual smoothie

comes out to .75 cents

now 9 times .75 cents equals 6.75 plus .75 cents because she bought a smoothie for herself

comes out to be $7.50

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
