masons dad paid $47.19 for the chalk and balloons.
masons dad paid $37.19 for the chalk and balloons.
masons dad paid $26.19 for the chalk and the balloons.
masons dad paid $36.19 for the chalk and the balloons.

Explanation:

Step1: Calculate total number of items

We need to buy for 10 friends and 1 for Mason, so total number of each item (chalk and balloon) is \(10 + 1=11\).

Step2: Calculate cost of chalk

Each chalk costs \(\$3.29\), so cost of 11 chalks is \(11\times3.29 = 36.19\).

Step3: Calculate cost of balloons

Each balloon costs \(\$1\), so cost of 11 balloons is \(11\times1 = 11\).

Step4: Calculate total cost before coupon

Total cost before coupon is \(36.19+11 = 47.19\).

Step5: Apply the coupon

There is a \(\$10\) off coupon, so the amount paid is \(47.19 - 10=37.19\).

Answer:

Mason's dad paid \$37.19 for the chalk and balloons.
