Multiples of 10.
Is that what you are asking?
(A) For x representing the cost of one of Tanya's items, her total purchase cost 5x. The cost of one of Tony's items is then (x-1.75) and the total of Tony's purchase is 6(x-1.75). The problem statement tells us these are equal values. Your equation is ...
... 5x = 6(x -1.75)
(B) Subtract 5x, simplify and add the opposite of the constant.
... 5x -5x = 6x -6·1.75 -5x
... 0 = x -10.50
... 10.50 = x
(C) 5x = 5·10.50 = 52.50
... 6(x -1.75) = 6·8.75 = 52.50 . . . . . the two purchases are the same value
(D) The individual cost of Tanya's iterms was $10.50. The individual cost of Tony's items was $8.75.
Answer:
87.8
Step-by-step explanation:
So you have to multiply 91 times 3.5 which equals 318.5
91 × 3.5 = 318.5
Then divide 318.5 by 100 which equals 3.185
318.5 ÷ 100 = 3.185
Next subtract 91 by 3.185 which equals 87.815
91 - 3.185 = 87.815
Last Round 87.815 to 87.8
87.8 should be the answer
Hope this helps
