Including a 19% sales tax, a tailored suit costs $357. Find the original cost of the tailored suit.
WITCHER [35]

Answer:

119/100 = 357/X

Step-by-step explanation:

since 357 is the price with the extra 19% tax, you can put 119 and 357 as numerators in a fraction because thats the price % of total cost with the tax, then have the denominators as the normal price without tax. so 119/100 bc 119 is the total cost % with tax, and 100 as the normal cost %. same for the opposite side, 357/X. 357 being the price with the tax and X being the price without the tax. so you just cross multiply to find X. so 100 × 357 (35,700) then divide the answer of that by 119 (35,700/119) to find X (300)

You are planning a promotion that will feature breakfast sandwiches. Your store normally sells 75 breakfast sandwiches per week.
EleoNora [17]
The number of additional sandwiches is 15.

If we multiply 75 sandwiches by 0.2 (20%), then we get 15, which would be the number of sandwiches needed to be sold to meet the sales goal.

Hope this helped.
