QuestionKadeem has \$9 and buys 7 cookies at \$0.50. How many donuts can he buy if he needs at least 10 total treats?

Studdy Solution

STEP 1

Assumptions1. The cost of a donut is 1.Thecostofacookieis1. The cost of a cookie is 0.503. Kadeem has $9 to spend4. Kadeem must buy at least10 items (donuts and cookies combined)
5. Kadeem decided to buy7 cookies

STEP 2

First, we need to find out how much money Kadeem will spend on cookies. We can do this by multiplying the number of cookies by the cost of each cookie.
Cost of cookies=Number of cookiestimesCost per cookieCost\, of\, cookies = Number\, of\, cookies \\times Cost\, per\, cookie

STEP 3

Now, plug in the given values for the number of cookies and cost per cookie to calculate the cost of cookies.
Cost of cookies=7times$0.50Cost\, of\, cookies =7 \\times \$0.50

STEP 4

Calculate the cost of cookies.
Cost of cookies=7times$0.50=$3.50Cost\, of\, cookies =7 \\times \$0.50 = \$3.50

STEP 5

Now that we have the cost of cookies, we can find out how much money Kadeem has left to spend on donuts. We can do this by subtracting the cost of cookies from the total amount Kadeem has.
Money left=Total money−Cost of cookiesMoney\, left = Total\, money - Cost\, of\, cookies

STEP 6

Plug in the values for the total money and the cost of cookies to calculate the money left.
Money left=$9−$3.50Money\, left = \$9 - \$3.50

STEP 7

Calculate the money left.
Money left=$9−$3.50=$5.50Money\, left = \$9 - \$3.50 = \$5.50

STEP 8

Now that we have the money left, we can find out the maximum number of donuts Kadeem can buy. We can do this by dividing the money left by the cost of each donut.
Number of donuts=Money left/Cost per donutNumber\, of\, donuts = Money\, left / Cost\, per\, donut

STEP 9

Plug in the values for the money left and the cost per donut to calculate the number of donuts.
Number of donuts=$5.50/$Number\, of\, donuts = \$5.50 / \$

STEP 10

Calculate the number of donuts.
Number of donuts=$5.50/$=5.5Number\, of\, donuts = \$5.50 / \$ =5.5Since Kadeem can't buy half a donut, the maximum number of donuts he can buy is5.
Kadeem can buy a maximum of5 donuts.
