Question

Maya has 60 caramel apples to sell. Each caramel apple iscovered with one topping.1/3 of the caramel apples are covered with only peanuts. 1/5 are covered with only chocolate chips.• The rest are covered with only sprinkles How many of the caramel apples are covered with onlysprinkles?

Answer 1

Let:

T = total apples

P = apples covered with only peanuts

C = are covered with only chocolate chips

S = apples covered with only sprinkles

`\begin{gathered} S=T-P-C \\ \text{where:} \\ T=60 \\ P=(1)/(3)\cdot60=20 \\ C=(1)/(5)\cdot60=12 \\ S=60-20-12=28 \end{gathered}`

------------------------------------------------------

Let's evaluate each value:

`\begin{gathered} -(1)/(2)x+3\ge5 \\ \text{for x=-6} \\ -(1)/(2)(-6)+3=3+3=6>5 \\ \text{This value satisfies the inequality.} \\ \text{for x=-4} \\ -(1)/(2)(-4)+3=2+3=5\ge5 \\ \text{This value satisfies the inequality.} \\ \text{for x=-3} \\ -(1)/(2)(-3)+3=4.5<5 \\ \text{This value doesn't satisfy the inequality} \\ \text{for x=1} \\ -(1)/(2)(1)+3=2.5<5 \\ \text{This value doesn't satisfy the inequality} \\ \text{for x=0} \\ -(1)/(2)(0)+3=3<5 \\ \text{This value doesn't satisfy the inequality} \\ \text{for x=2} \\ -1+3=2<5 \\ \text{This value doesn't satisfy the inequality} \end{gathered}`

-6 and -4 only
