79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100

100-12 = 98

We have to figure out what 88% is

79.30 ---- 100%
X ------------ 88%

Cross Multiply

79.3× 88 = 100x

6978.4 = 100X

69.784 is without taxes

69.784 = 100% {100% because it is the total price.}

69.784 = 100%
X --------- 6.25%

Cross Multiply

69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615


69.784 + 4.3615
74.15 is the answer
