Answer:
Luis has 30 cards
Step-by-step explanation:
To solve this problem, we need to setup a system of equations.
If we call the amount of cards Juan has "J", Pedro "P", Maria "M" and Luis "L", we have that:
J + P + M + L = 62
P = J/3
M = J - 3
L = 2J
Substituting P, M and L in the first equation, we have:
J + J/3 + J - 3 + 2J = 62
13J/3 = 62 + 3
13J = 65 * 3
J = 15 cards
The amount of cards Luis has is:
L = 2J = 2 * 15 = 30 cards
Answer:
9 tables (see below)
Step-by-step explanation:
Let t represent the number of table sales required to meet revenue requirements. The total of sales for the day must be ...
7(200) +t(800) ≥ 8000
800t ≥ 6600 . . . . . . . . . . subtract 1400
t ≥ 8.25
If additional sales are limited to tables, the store must sell at least 9 tables. The revenue goal can also be met by selling 1 chair and 8 tables. (A chair brings in 0.25 times the revenue of a table.)
If the store sells 5 more chairs, it only needs to sell 7 tables. (This combination will result in 19 pieces being sold.)
Answer:
0.10
Step-by-step explanation:
Technically it's 0.12 but I only say this because they rounded by from 58 to 60 in their question
