Answer:
Miss Bloom spent $48.47 in total
Explanation:
turn 7% into a decimal --> 0.07
multiply the cost of art supplies by the tax % (in decimal form)
45.30(0.07) = 3.171
add 3.171 to the original cost of art supplies
45.30 + 3.171 = 48.471
round to the nearest hundreths place (since money typically only has 2 decimal places)
48.471 --> 48.47
therefore, miss bloom spent $48.47 in total
