To find the sale price, we have to first find the discount amount. The discount amount can be found by multiplying the regular price by the discount rate.
Discount amount = $112 x 35% = $112 x 0.35 = $39.20
Now, subtract the discount amount from the regular price to get the sale price.
Sale price = $112 - $39.20 = $72.80
2. A $16.36
To find the tip, we have to find 18% of the total cost of the meal.
Tip = $98.50 x 18% = $98.50 x 0.18 = $16.36
3. A $3.85
The gas price increased by 17%. To find the new price, we first find the increase in price.
Increase in price = $3.29 x 17% = $3.29 x 0.17 = $0.56
Now add the increase in price to the original price.
New price = $3.29 + $0.56 = $3.85
4. B $340
To find the simple interest after one year, we can use the formula: Interest = Principal x Rate x Time.
Interest = $8,500 x 4% x 1 = $8,500 x 0.04 x 1 = $340
5. B $17.79
First find the total cost of the meal before tax: $5.75 + $11.45 = $17.20
Now find the sales tax: $17.20 x 5% = $17.20 x 0.05 = $0.86
Add the sales tax to the cost of the meal: $17.20 + $0.86 = $17.79
6. C $1650
To find the interest John will earn in 25 years, we can use the formula: Interest = Principal x Rate x Time.
Interest = $3,300 x 2% x 25 = $3,300 x 0.02 x 25 = $1,650
