Answer:

Multiply the number of items #w# and #b# by the price of each item to get

#4.95w+.30b#

Explanation:

#w# and #b# represent the number of wrenches and bolts purchased, so you want to multiply each variable times the price of that particular item. For example, the cost of #w# wrenches is

#4.95*w#

and the cost of #b# bolts is #.30*b#

Put this together to get

#4.95w+.30b#
