Use the Four-Step Approach to solve the given problem.

V125BC [204]

Answer:30 mi

3s = 2.5(s+2)

3s = 2.5s + 5

3s - 2.5s = 5

.5s = 5

s = 5/.5

s = 10 mph to the beach

Confirm this by finding the actual distance each way, should be the same

3*10 = 30 mi

The middle school basketball team is selling t-shirts for $12.50 each to raise money for new uniforms. They have already sold 40

Rama09 [41]

Step-by-step explanation:

given:

$12.50- the price of the tshirts

40- the tshirts they have sold

$850- the raise they need

solve:

$12.50 × 40 = $500 (the price of tshirts and tshirts they have sold)

$850 - $500 = $350 (the raise they need and the money they have so far from the 40 tshirts they have sold)

$350 ÷ $12.50 = 28 (the money they lack and the price of a tshirt)

answer:

thus, they need to sell 28 more tshirts to have the raise of at least $850

hope this helps, good luck! :)
