We are given expression for cost of admission at an amusement park : 15a+12c.
Where a is the number of adults and
c is the number of children.
We need to find the total cost of 5 adults and for 10 children.
<em>In order to find the total cost of 5 adults and for 10 children, we need to plug a=5 and c=10 in 15a+12c expression.</em>
Plugging a=5 and c=10 in 15a+12c expression, we get
15(5) + 12(10) = 75 + 120 = $195.
<h3>Therefore, the total cost for 5 adults and for 10 children is $195.</h3>
Hello!
First you have to make the denominators the same so the numbers are comparable.
You can multiply the top and bottom number in 2/3 to get 6/9
Now you add
4 6/9 + 3 1/9 = 7 7/9
The answer is 7 7/9
Hope this helps!
Answer:
Step-by-step explanation:
Let x represent the amount of medical bills that Giselle has to pay.
Assume she has over $160 in bills,
it means that
x > 160
Under plan A, Giselle would have to pay the first $110 of her medical bills, plus 35% of the rest. Therefore, she will have to pay for
35/100 × (x - 110) = 0.35(x - 110)
Under plan B, Giselle would pay the first $160, but only 20% of the rest. Therefore, she will have to pay for
20/100 × (x - 160) = 0.2(x - 160)
Therefore, the amount of medical bills that plan B will save is
0.35(x - 110) - 0.2(x - 160) = 0.35x - 38.5 - 0.2x + 32
0.15x + 6.5
Substituting x = 160 into 0.15x + 6.5, it becomes
0.15 × 160 + 6.5 = $30.5
Total bills would be 160 + 30.5 = 190.5
Therefore, Giselle would save $30.5 with plan B if she had more than $190.5 in bills.
