Mr. Langly bought a pair of slacks for $59.90. He also bought a pair of boots for $89.90. What was the total cost of the slacks and boots, including an 8% sales tax?

Step-by-step explanation:

Given that Debbie has a pack of cards numbered from 1 to 20. She picks four different number cards. Exactly three of them are multiples of 5.Exactly three of them are even. All four of the numbers add up to less than 40

3 of them are multiples of 5 and 3 of them are multiples  of 2.

Hence atleast two should be multiples of 10

Hence 10,20 are two numbers

Since sum is less than 40 multiple of 5 can be only 5

Next number can be 2 or 4

Hence the numbers would be

2,5,10,20 or

4,5,10,20
