Step-by-step explanation:
<u>Step 1: Define Equation</u>
6n + 7 = 55
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 7 on both sides: 6n = 48
- Divide 6 on both sides: n = 8
<u>Step 3: Check</u>
<em>Plug in n into the original equation to verify it's a solution.</em>
- Substitute in <em>n</em>: 6(8) + 7 = 55
- Multiply: 48 + 7 = 55
- Add: 55 = 55
Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.

Answer:
<u>Marcelino will have $7.50: his costs are more than his profits. </u>
Step-by-step explanation:
22.50 + 7.50 + 15.00
In total Marcelino spent $45 to make these balloons.
He wants to sell each balloon for $1.25.
If he sells the 30 balloons he bought for $1.25 he will make:
30 * 1.25 = $37.50... okay he made some money, BUT he spent $45 dollars for the items.
45 - 37.50 = $7.50, Marcelino made no profit... he still needs to make $7.50 to pay off his own costs.
