Answer: Lena saved up $3,475 in 25 weeks


Step-by-step explanation:

150 + 532 = 682

682/4 = 133

133 x 21 = 2,793

2,793 + 682 = 3,475

Hope this helps :)

A store charges 6% VAT on all sales.<br>What is the total cost of a shirt marked at $30​
AURORKA [14]

Answer:

$31.8

Step-by-step explanation:

Assuming the 6% tax is separate from the $30, we can use this equation:

Total = Cost + Tax  (pretty self explanatory)

Method 1

Total = $30 + (6% * $30)

Total = $30 + $1.8

Total = $31.8

Method 2

Total = $30 * 1.06          (The 1 is the original cost, the .06 is the 6% tax)

Total = $31.8

Evaluate the expression when d = 20 and v = 19 20v + 12d - 6v
Alexeev081 [22]
D = 20 , v = 19
20v + 12d - 6v
= 20 (19) + 12 (20) - 6 (19)
= 380 + 240 - 114
= 620 - 114
= 506
When d = 20 and v = 19
20v + 12d - 6v = 506
